Electronically Assisted Astronomy (EAA) has been around for a while. Not long ago, you'd get into it by buying a camera, attaching it to your eyepiece, hooking it to a monitor, and then watching as it combined - or "stacked" - images of nebulae or galaxies. Before long, the image on the monitor would take on the recognizable shape and color of a deep space object that, viewed unaided through the eyepiece, appeared as little more than a barely-perceptible smudge.

Gone was the romance of peering at the space beside that smudge (using averted vision) and imagining, say, the combined light of 250 billion stars. But, if we're being honest, the magic got a little stale when squinting at one equally dim blob after another. EAA offered no substitute for looking through a big Dobsonian under a dark sky. Its images paled in comparison to those that could be taken with a complicated astrophotography rig. But for those of us stuck in the city and unwilling or unable to try serious astrophotography, EAA let us see what otherwise seemed out of reach: the universe beyond our solar system.  

A few years ago, two startups - Unistellar and Vaonis - took the obvious next step by debuting an integrated telescope, go-to mount, tripod, and stacking camera. Both the EVScope (Unistellar) and Stellina (Vaonis) were small, portable, and remarkably easy to use compared to any telescope on the market. Both were priced far beyond the cost of their parts; it is, after all, expensive to sell a niche product as a brand-new company. Still, despite the exorbitant cost - I shudder to think of what I paid for my EVScopes - enough people bought the new "smart" telescopes that both companies seem to have prospered. 

When both the EVScope and Stellina succeeded, it was clear that amateur astronomy would never be quite the same. The technology would keep improving, and bigger, more established companies would get in the game. A maturing market, meanwhile, would permit economies of scale. Those who waited on getting the first-generation EVScope or Stellina reasoned - correctly - that prices would soon collapse. 

Anyway, I bought my EVScope 2 for about $5,000. Recently, Vaonis released its next-generation Vespera II for about $1,600. The Vespera II is much more compact, it has a more sensitive sensor, it focuses itself (unlike the EVScope), and it's built around an apochromatic refractor that, in theory, should yield sharper images. I sold my EVScope and used the funds to purchase the new Vespera - and a few other things, because wow that price difference is huge. 

These are two approximately 10-minute exposures of the Orion Nebula. Atmospheric transparency and seeing were about average - maybe a little worse than average - while I took the picture on the left. Both conditions were definitely above average while I captured the shot on the right. Believe it or not, Orion was also much higher in the night sky while I took the picture on the right than when I took the image on the left.

Of course, I took the picture on the left with the $1590 Vespera II and its $229 light pollution filter, while I took the image on the right with the EVScope 2, which is now on sale for $4,409. The Vespera focuses itself, but I'd carefully collimated the EVScope before using. I expected a difference in performance, sure, but the magnitude of that difference still astonished me. 

Actually, these pictures do not reveal the biggest distinction between the two images. Because of the Vespera's shorter focal length and more sensitive sensor, its images capture far more of the night sky. In fact, its new "CovalENS" feature allows for the integration of multiple stacked images of adjacent corners of the night sky, which should enable sweeping mosaics of, say, the entire Andromeda Galaxy. And I should emphasize again that the Vespera is much smaller and more portable than the EVScope.

Admittedly, the EVScope comes with a tripod, while the Vespera does not (though again, the Unistellar backpack is much pricier than the one offered by Vespera). And the EVScope does have other advantages over the Vespera. It has an eyepiece, so if you want to use it like a regular telescope, you can. As I've often reported in these pages, the view through the EVScope eyepiece looks better than the pictures, though I suspect this is partly because the image is smaller. Magnifying the image on the bigger screen of a phone - let alone an iPad or laptop - reveals its imperfections.  

The Vespera also looks like something built by Apple, seemingly to appeal to buyers who see Apple as the gold standard for sophisticated, problem-free technology. It's a problem. The telescope's sleek surface is slippery and difficult to handle, especially in the cold. Screwing it into or out of a tripod is frightening. It wobbles dangerously and threatens to plummet to the ground (not a problem with the EVScope). It's also easy to accidentally open the Vespera, since there's nothing to lock the optical tube in place until needed, and the power button is far too easy to activate while holding the telescope. The button shines with a bright blue light when it's on. That will be familiar to users of common consumer products, but any amateur astronomer will tell you that a bright blue light is exactly what you don't want as your eyes adjust to the dark. Unlike the EVScope and other competitors now on the market, in important ways the Vespera prioritizes form over function. 

There's more. Whereas the EVScope has no problem with nearby street lights, the Vespera's lack of a dew shield allows those lights to easily create distortions in the image. Horizontal lines at the top corner of my images, I was told, are the product of a nearby (but not particularly bright) light. The lack of a dew shield is also, of course, a ticket to frustration in cold or humid climates (Washington, DC can be both). Vespera sells a screw-in Hygrometer Sensor - for an extra $119. 

Then there's the lack of citizen science. Unlike Unistellar, Vespera has no fancy partnerships with the big guns in space science. If you want to join my friends at the SETI Institute in searching for exoplanets, you're out of luck. And if you want to help NASA track its spacecraft, stick to the EVScope. 

The biggest problem with the Vespera II, however, is battery life. The EVScope 2 can keep imaging for up to nine hours, and other Unistellar models  do even better. By contrast, the Vespera has four hours of battery life - supposedly. I found that its battery consistently dropped down to 85% capacity after I had set it up, which takes over five minutes (setup was much quicker with the EVScope 2). In subzero temperatures, I suspect I could squeeze about three hours out of the telescope. Storage capacity is also much lower in the Vespera II, compared to the EVScope 2, but to me that doesn't matter; I always move good pictures to my phone's photo album. 

So do the many little shortcomings of the Vespera II, relative to the EVScope 2, overwhelm the advantages of its sharper, bigger, more colorful images, its autofocusing, and its more portable size and weight? The answer is: no, not even close. At present I think the new Vespera is simply a much more capable telescope, and again: it's sold at a fraction of the cost. In fact, I now fear for the future of Unistellar. The likes of Celestron and ZWO are offering telescopes that target both the high and low ends of the smart telescope market. I suspect that, if Unistellar stays in business, it will owe a lot to the connections its founders wisely made with SETI and NASA. 

I should say that I've reached my conclusions primarily by observing the Orion Nebulae. Planetary images, I suspect, are better with the EVScope 2 than the Vespera II, owing in part to the former's greater focal length and aperture. But that's really not why I'd want to use EAA. Even my C90, for example, gives a vastly better view of Jupiter than the EVScope could provide at twenty times the cost. 

Of course, as I've often described in these pages, all smart telescopes have the same shortcoming. To use them you wait around and stare at a screen. There's still something different - something special - about looking through a glass eyepiece instead, at age-old light at it shimmers through our roiling atmosphere. 

If November isn't my favorite month to observe here in Washington, DC, it's right up there with March and April. Most nights are cool, crisp, and imbued with an ineffable fragrance - of decaying leaves in autumn, of budding blossoms in spring - that encourages deep breaths. The mosquitoes are resting after (or before) the horrors of summer, and seeing hasn't yet slumped to its winter lows.

I try to use my telescopes as much as I can in late autumn and late spring, but there's a problem: these are the busiest times in the academic calendar, and it's not always easy to juggle my hobby with my work. Worse, both seasons are times of unrelenting illness for any parent with young children. So it is that while the sky has been routinely clear for the last month, with seeing typically average, I haven't had much chance to exploit it.

Finally, on November 13th, I felt just healthy enough to venture outside with my TSA 120. At just before midnight, Jupiter was nearing zenith. Although atmospheric conditions were not exactly ideal, I couldn't pass up the chance to have a look. 

I had let my TSA 120 sit outside for about 45 minutes before using it, and it paid off: while temperatures were no higher than 10 degrees Celsius, the telescope had completely cooled down. Yet when I turned to Jupiter, the planet initially resembled a circle of bubbling milk, surrounded by a smattering of drops (the Galilean moons). Why had I sacrificed sleep for this?

Then, as I considered packing up, the atmosphere abruptly stabilized - and now a staggering wealth of detail shimmered into view. It was fleeting - "revelation peeps," to use a Lowellian term, often are - but it was more than enough to keep me glued to the eyepiece. Over the next hour, belts, zones, and the Great Red Spot all flickered across the pale Jovian disc, and I nearly lost track of time. Finally, it dawned on me that even a bad night's sleep was slipping away, and I hastily carried my equipment inside. 

Perhaps it's a character flaw that I like to obsessively compare my instruments; if so, it is a flaw I share with most amateur astronomers. In this case, I couldn't help but reflect on the TEC 140 I once owned. In a vacuum, I might prefer that telescope over the TSA 120. But the difference in the optical performance of both telescopes is slight enough that I prefer the far greater portability of my TSA 120 setup. It weighs half as much, and that makes it so much easier to use when I'm tired. 

Of course, when it comes to portability and ease of use it's hard to beat my EVScope 2. With Orion starting to rise high above the horizon in the wee hours of the night, I decided to use that telescope to view the constellation's famous nebula. On the 18th I parked the telescope in my backyard, found a gap in the increasingly bare trees, and had a look. 

As usual, within seconds the EVScope delivered a view that no traditional telescope could match under an urban sky. Yet using the telescope so soon after observing with my TSA 120 gave me a clear sense of what bothers me about it. The EVScope is easy. There are no "revelation peeps" - no flashes of transcendence - because everything is smoothed out in a (relatively) pretty picture. There's no craft to observing, no sense of taking in the universe with your own eyes. You see more - but you feel less. 

Sometimes, that's okay. There are whole classes of object - white dwarfs for example - that I can only glimpse with my EVScope (at least in our light-polluted skies). Yet if I were forced to give up one telescope, I would choose the EVScope without a second's hesitation. 

My health improved this week, and my workload (temporarily) eased. Now I steeled myself for a challenge I've dreaded for weeks: collimating my new Mewlon 210. I've been so unwilling to try it that I even - very briefly - placed the telescope for sale. Yet I read up, prepared my Allen key - and left the Mewlon out for an hour to cool down. 

When I returned outside, I found that the telescope still had not completely acclimated to temperatures that were not far above freezing. I waited another half hour, then tried again. Now the telescope seemed cool enough, but to my surprise my first view of a star was so underwhelming that I again considered whether to sell the telescope. A blob is the best I could get - a far cry from the pinpoints I see through my refractors. 

I'd hoped that I'd been wrong about the Mewlon's collimation, but now there was no doubting it: the telescope's secondary mirror simply did not perfectly align with the primary. I set to work tightening bolts, and to my surprise I didn't mind it. Years of tinkering with mechanical watches and bicycles had prepared me well, I suppose, because after 15 largely painless minutes I was just about done. 

I could scarcely believe my eyes when I returned to that star. Instead of a blob, there was a perfect little diamond. To my amazement, the telescope's diffraction spikes - a product of the four vanes that hold its secondary mirror - actually added to the star's beauty. It wasn't perfect - seeing was actually below average - but it was about as beautiful a stellar image as I can remember seeing. 

Jupiter offered some of the same revelation peeps I'd enjoyed with my TSA 120, except with a bit more color (and this time, the diffraction spikes were a bit distracting at lower magnifications). Turning to the Trapezium in Orion clearly revealed five, perhaps six stars - a challenge for fine optics even in good seeing - but it was Betelgeuse that truly stole the show. The star was simply a spectacularly beautiful orange gemstone when viewed through the Mewlon. The telescope's large aperture (compared to my refractors), total lack of false color, and yes, diffraction spikes made me appreciate simple stars as I never have before.

With any luck, I'll use the Mewlon to spend happy hours admiring the double stars that are easily visible in our city. But on this night, it was time to pack up - and to banish all thought of selling the Mewlon. 

Recently, I've been on a mission to optimize my grab-and-go setup. Slowly but surely, parks that offered dark corners for a telescope have been saturated with bright lights: the kind that needlessly waste energy, confuse nocturnal animals, and pollute the night sky. I have to walk further than I have before, or settle for less than ideal observing conditions. To that end, setups that used to feel perfectly mobile now are discouragingly cumbersome to use. 

I admit I was tempted to swap my FC-100DZ for a lighter telescope, such as the FC-100DC I used to have and love. Then I had an epiphany - one I should have had long ago. With its diagonal removed and dew shield retracted, the DZ is just over two feet long. Couldn't I find a padded bag that long? If so, the DZ would be as easy to transport as my dearly departed TV 85, while offering considerably better performance. 

I found the bag - for just $23! - and wow: what a difference. It's strange but true: the DZ is as transportable as much smaller telescopes, but offers truly stunning views of everything that shines through light-polluted skies. The other night, I pointed it at Saturn, which is just now reaching opposition (its closest annual approach to Earth). The view was spellbinding, with glimpses of detail in the planet's clouds that were among the finest I've seen. On the other hand, DC's summer mosquitoes did not give me a moment's rest, and I was grateful that my little setup takes just a few minutes to disassemble. 

Then, last weekend, it was off for what has become an annual trip to the beach near Lewes, Delaware. I brought my EVScope 2, eagerly anticipating darker skies. Unfortunately, I soon found that atmospheric transparency was lower near the beach than it has been in years past - owing, once again, to that wildfire smoke. Worse, my recent experience with a truly pristine sky in Manitoba left me unimpressed with the view in Delaware. Sure, the Milky Way was barely, and I mean just barely, visible after fifteen minutes outside in the dark. But there was simply no comparison. 

I occasionally fantasize about selling my EVScope in exchange for a more capable astrophotography setup. The three (!) clear nights I experienced in Lewes reminded me why I have that fantasy - and why I haven't acted on it yet. 

First, the telescope needed collimation. If you've read any reviews of the EVScope, you'll know that some complain about the need to collimate such an expensive gizmo. Let me assure you that it's much easier than collimating an SCT, for example. Even when the telescope is badly misaligned - as it was for me in Lewes - the entire process takes a few minutes at most.

The real problem is that Unistellar's instructions include a glaring error. To collimate the telescope, it should not be pointed at a particularly bright star - I tried Antares - because the star's brilliance will not allow you to see the secondary mirror when out of focus. I suppose it's a minor detail, but this little mistake can create a lot of frustration. 

Usually, it takes just moments to align the EVScope and get it ready to slew to any object you can imagine. Usually. On one night in Lewes, I had to turn off the telescope a couple times before it aligned itself. On two other nights, it did not precisely center objects after finding them - so that, at the telescope's highest magnifications, objects were simply offscreen. 

On a third night, everything worked seamlessly. I carefully leveled the telescope, collimated it, and waited over thirty minutes for it to acclimate. That may not sound arduous to veteran amateur astronomers - but it's hardly ideal for a grab-and-go setup. 

When the telescope is aligned, it tracks objects seamlessly. The trouble is that its altazimuth mount cannot perfectly track stars on long exposures. This isn't visible while peering into the eyepiece, but it does show up clearly in astrophotographs taken with the telescope. Since most people will use the telescope by staring at their phones or tablets - in fact, some Unistellar models don't even have eyepieces - this is a serious limitation. Even this six-minute exposure of the Eagle Nebula has distorted stars. 

Stars are also distorted - even through the eyepiece - because stars shimmer in all but the steadiest atmospheric conditions. When using a traditional telescope - especially a refractor - you may see a roving, flickering pinpoint. Yet the EVScope takes exposures to provide its bright views of deep space objects, and in these exposures the undulating pinpoints that are stars in mediocre seeing all congeal into blurry blobs.

For a refractor aficionado like myself, the effect is deeply unsatisfying. To me, it really does not feel like you are actually peering into space when you use an EVScope. Occasionally I wonder: what am I getting here that I could not obtain by finding images on the internet? Have a look at this shot of the Wild Duck Cluster, for example. 

The problem is compounded by the reality that Unistellar's software cannot quite compensate for the effects of light pollution. Overall, it does a remarkable job - I'm still amazed that I can admire the Triangulum Galaxy from downtown DC, for example - but there's still a good deal of noise even under a Bortle 4 or 4.5 sky (as in Lewes). Have a look at this 24-minute exposure of the Pinwheel Galaxy, and notice the noise. 

Another inconvenient truth is that, even with the galactic core above the horizon in the summer, there just aren't that many objects that truly impress when viewed with the EVScope. You have to remember that although the EVScope allows you to view galaxies and nebulae that are far beyond the reach of a comparably-sized traditional telescope, it is also incapable of providing satisfactory views of many objects that such a telescope would reveal. Open clusters, double stars, the Moon, and the planets: everything that impresses when seen through a telescope like the Takahashi FC-100DZ is underwhelming at best when viewed with the EVScope. In practice, dozens of objects in the EVScope's catalogue look like this, and hundreds are far less impressive. 

The EVScope also seems to have a weak wifi signal. Walk twenty feet away, and you're likely to lose it. You can forget about sitting indoors while operating the telescope. That's too bad, because mosquitoes really can make it hard to stay outside in our muggy summers. In other places, winters are just too cold for comfortable observing. Wouldn't it be easy for Unistellar to include some way of amplifying the wifi signal on its $5,000 device?

So yes, I was getting a little annoyed in Lewes. I kept imagining what my TEC 140 might reveal; not nebulae in a distant galaxy, sure, but pinpoint stars on a velvety black background, and spectacular planetary views. This is the best that the EVScope can do on Jupiter, even after a recent software update that dramatically improves planetary performance. ​

I admit: I could go on. Suffice it to say that my nights in Lewes reminded me that, if you buy an EVScope, you really should go for the EVScope 2. This is because the eyepiece is really a lot better than some reviews suggest. Somehow, images of nebulae and galaxies are much brighter and sharper through the eyepiece than they appear to be when viewed on a phone or tablet.

The distortions I complained about above - those blurred stars, in particular - are also minimized when viewed through the eyepiece, likely because the small scale of the image mitigates them. As a result, I am consistently impressed by the nebulae and galaxies I see through the eyepiece; so impressed that I take an image that then disappoints. 

Just before I took the image of the Pinwheel Galaxy that you've already seen, I invited my wife and our friend outside to have a look. Both are astronomy novices, to put it mildly. Both seemed skeptical that they'd see much. Yet when both craned over the EVScope eyepiece, they gasped. They could not believe that they had seen a whole galaxy across 20 million years in time and space. They kept saying how cool it was. 

"It's almost like one of those picture slide viewers," my friend eventually said. Indeed. You see so much more - and so much less - than you would with an ordinary telescope. That is why I think I'll keep the EVScope . . . for now. 

Here are some extra images, showing medium-length exposures of some of the best-known sights in the summer sky. 

To put it mildly, it's been a dreadful summer for astronomy in Washington, DC. The primary culprit is wildfire smoke, which seems to waft into the city with every clear night. As a professor whose primary preoccupation is climate change - and as a dad - the smoke fills me with dread. It is alarming for any number of reasons, but it has extra significance for those enamored with the night sky. The atmosphere is likely to be less transparent on a warming planet, owing either to wildfire smoke or aerosols intentionally seeded into the stratosphere.

That second possibility is known as solar geoengineering. It's cheap (compared to the cost of global warming), it's likely to be effective (despite a litany of troubling side effects), and I'm increasingly convinced it will happen within twenty years. In fact, this summer the White House Office of Science and Technology Policy released a primer that more or less accurately describes where the science of geoengineering currently stands. If plans currently on the drawing board someday take off, astronomy as a science and hobby will change - quite possibly for the rest of our lives. In all likelihood, planetary observation won't change much, and Electronically-Assisted Astronomy will still reveal deep space marvels. Yet my suspicion is that traditional telescopes - including big Dobsonian reflectors - will be far less effective for observations of diffuse objects far from our Solar System, such as nebulae or galaxies. You've been warned! 

Anyway, I did manage to see one spectacular sight in DC this summer. In May - just before the worst of the smoke surged south - a supernova exploded in the Pinwheel Galaxy. I hauled my EVScope to a nearby field and had a look. The above picture is all I managed to capture, but the view through the eyepiece was far more impressive. I still can't believe I managed to see an exploding star - and, in all likelihood, the formation of a black hole - 21 million light years from Earth. 

More recently, I travelled with my family to Winnipeg. Despite its closer proximity to the many wildfires burning through British Columbia, the city has been less affected by wildfire smoke than Washington, DC. The sky is not quite free of smoke, but it's a good deal more transparent than it's been further south. 

This was my first trip to the city since the pandemic, and I'd nearly forgotten that I cobbled together a fairly impressive little observing setup here. Four years ago, I had a Twilight I mount delivered to my in-laws. I also purchased a C6 shortly after I was last here, and it was still in the box when I arrived this time. I unpacked it with some trepidation - the last C6 I purchased was damaged upon arrival - but not to worry: to my relief, the little telescope was in perfect condition. 

With everything assembled, I was struck by how well the C6 fits on the Twilight mount. I don't think it could handle a C8, but a C6 is just about perfect. It's quite stable, convenient to look through, and remarkably easy to move. In fact, I can lift mount, tripod, telescope, diagonal, and eyepiece - everything - above my head with ease. 

​I swapped out the standard Celestron diagonal - a child's toy - with a TeleVue Everbrite, and used a Baader Mark IV Zoom for an eyepiece. The field of view, I must admit, is a little too narrow, but then a Schmidt–Cassegrain really isn't a wide-field instrument.

I was gifted one clear night after another since arriving here, and used the first two nights to admire the Moon. This far north, it doesn't rise far above the horizon right now, and it is tinted a beautiful pinkish-gold by the diffuse smoke in the upper atmosphere. Seeing was mediocre at best, but the telescope turned out to be well collimated, and the view was quite striking.

As the above image attests, the Moon was not as sharp as it would be through one of my refractors. Even in mediocre atmospheric conditions that prevailed here, the Takahashi, I'm sure, could have shown me more. But when you consider the relatively low cost of a C6 - albeit much higher than it was pre-pandemic - the telescope is a remarkable performer. I was particularly impressed by how cleanly it snapped into focus; in fact, finding focus seemed a little easier with the C6 than it is with my refractors. 

I was genuinely delighted to discover that Saturn now rises high enough above the horizon to observe at around midnight. The planets might have drawn me outdoors this summer despite the wildfire smoke, but often they had set before I could step outside. Well - Saturn, at least, is back.

The C6 offered a really satisfying view of the planet, with the Cassini Division clearly visible at 75x. I'm not sure my Takahashi would have done that much better, given the seeing. In a cooperative atmosphere, I have no doubt that the refractor would outpace the Schmidt–Cassegrain; there is a delightful crispness to its views that the stubbier telescope can't quite match. And of course, it never needs to collimate or acclimate (for long).

​Nevertheless, I was stunned when, later, the C6 showed me Arcturus as a perfect orange point: something I had not expected from a Schmidt–Cassegrain. For those less obsessed than I am with getting the absolute best views that a (modest) aperture can provide, I suspect it would be impossible to justify the extra cost of a 4" apochromatic refractor over a C6. Well done, Celestron! 

Anyway, I had a truly wonderful half hour on the porch, the crickets chirping nearby as I admired the ethereal beauty of Saturn's rings. I was struck by how much their tilt relative to us has changed over the past year, and I fear that they will - briefly - disappear from view entirely in the months to come.

It will be fleeting. Soon enough, the rings will return, and the planet will regain its grandeur. For me, one of the joys of astronomy lies in the knowledge that however badly we muck up our planet, countless wonders glitter beyond our reach. With or without us, it's a beautiful universe. 

For amateur astronomers, two things happen to the atmosphere around this time of year in Washington, DC: in general, transparency improves, and seeing - meaning, of course, stability - deteriorates. Daytime brings deep blues, sunset a beautiful gradient from azure to scarlet, and nighttime brilliant winter stars in a velvet tapestry (when not facing towards the National Mall, at least). At the same time, the stars noticeably twinkle far more than they do in summer, and moments of steady seeing become ever rarer. The muggy, mosquito-plagued nights of summer, when the planets can very occasionally look like little Hubble photos viewed from afar, are now a distant memory. 

All the same, since keeping this blog I've found autumn to be my favorite time to observe. It's just so much more comfortable being outside, the planets are still high in the sky, and my refractors at least give me a puncher's chance of making out some detail on them, even in nights of mediocre seeing. 

With that in mind, I stepped out on the 14th, Takahashi in hand, and found a nook near my mostly tree-covered backyard that afforded me a good view of Mars. It was cold by DC standards - around freezing - but my telescope was well acclimated and the view was beautifully sharp. The Martian south pole in particular looked large and sort of smeared; not quite as brilliant as it can, but larger in dimensions. Later, a spectacular set of pictures posted by Peter Gorczynski over at CloudyNights.com revealed the cause: a swirl of clouds around the pole that were barely visible to me in the mediocre seeing. 

I didn't last long in the cold weather, and over the next week seeing here in DC grew worse - but transparency remained better than average. I decided to test out the Unistellar EVScope 2 on the comparatively few but spectacular deep space objects that are beginning to climb high above the horizon in our late autumn sky. 

On the 22nd, I marched about 20 minutes uphill from my house to my daughter's school. Its field is now the nearest I know that is not completely saturated with light, and I can only hope it stays that way. It's not hard to haul the EVScope that distance, thanks to the relatively ergonomic backpack it comes with, and I can only emphasize yet again how absurdly easy it is to set up the telescope once I'm in position.

It takes no more than a minute to have the EVScope fully aligned and tracking my first target. It quickly and easily hooks into its tripod, immediately connects to my phone, and in just moments aligns with the night sky and slews to my first target. It takes me two or three times longer to set up my refractors on their sample manual mounts, which of course don't have any software at all. Other tracking amounts, even the simplest ones (such as the iOptron AZ Mount Pro I own),  require far more steps to set up, and often don't quite align perfectly; it's why I inevitably favor manual mounts when stepping out with my refractors. I'm not sure how Unistellar leapfrogged all the established brands in amateur astronomy by offering a mount that truly is plug and play - but they have, and it's wonderful. 

After I let the telescope cool down, I turned to the Orion Nebula. In the past, I've tended to focus too much on my phone while the telescope slowly integrated its pictures and the view of my target gradually brightened. This time I favored the eyepiece, which as I've written elsewhere is much improved on the EvScope 2. I now noticed that the eyepiece view seemed much sharper and, to my surprise, three-dimensional than the image on my phone. The dark nebula jutting in front of the familiar crescent of the Orion Nebula, for example, truly looked as though it was in the foreground, and I followed a fascinating zigzag pattern of dark nebulosity weaving across the bright core that mostly washed out in the phone image.

The EVScope permits easy if relatively low-resolution astrophotography, but the current iteration at least is really designed for observing. I've complained that using the EVScope is a very different experience from using a traditional telescope, because I've tended to wait around for the images to integrate on my phone. This time, I was glued to the eyepiece - and it really did feel like a proper observing experience. 

The EVScope 2 improves considerably over its predecessor, and the Unistellar software has continually added new capabilities. Just have a look at the image of the Orion Nebula that I took almost exactly two years ago, and compare it with this week's version. I suspect I could further improve the view through the EVScope 2, and I wonder what it would look like were I truly under a dark sky. Still, I find the progress to be really exciting. 

Just last night, I learned that Unistellar had released yet another software update: this time to enable planetary observation. I couldn't resist, and marched back to the same field. This time, however, I was a little disappointed. While the telescope for the first time automatically dimmed its images of Jupiter and Mars and showed real details on both worlds, overall the view was of course radically different from what I see through my refractors. While traditional telescopes may not as clearly reveal the cloud bands of Jupiter, for example, they show far finer and subtler detail; far more realistic and impressive coloration; and of course the moons and stars surrounding the planets. 

I expected as much, but in the moment I couldn't help but be underwhelmed. Yet while walking home, I considered where the technology might be in another two years. Eventually, I suspect there will be few if any areas where traditional telescopes reign supreme. To me, their greatest value could then lie in the connection they provide to generations of observers stretching back to Galileo: to a history of often-eccentric women and men straining at odd hours to discern barely perceptible truths hidden across unimaginable distances in time and space. There are some things clever software can never replace - not many, perhaps, but some. 

It was Father's Day yesterday, and I had sanction to wake up late. When I found out the night would be clear, I was full of anticipation - until I realized that seeing was forecast to be about as bad as I can remember. I stepped out after sundown, however, and found the stars unusually visible in the night sky. Sure enough, transparency was high above average - which made sense, as the night as unusually crisp for a DC summer. 

Out I stepped at around 1:30 AM, burdened like a Tolkien dwarf with the EVScope II on my back, and a tripod in hand. This time I walked to a nearby school's soccer pitch, which not only affords an impressive view of the whole sky but is also (strangely) bereft of street lights. I set up in a few seconds, then targeted the heart of the Milky Way as it rose well above the southeastern horizon. The light pollution is very bad in that direction - it's right above the National Mall - but still, I had high hopes. 

I've largely praised the EVScope in these pages, and rightfully so. In a matter of moments the Omega Nebula emerged from the background light pollution, and wow that is an impressive effect. After a five-minute exposure, I moved on to the Lagoon Nebula, with much the same results. I now slewed to the Owl Nebula, but this time the view underwhelmed - even after five minutes - and it's not surprising: at around tenth magnitude, it's a challenge for the EVScope in light-polluted skies. As the chill began to set in, I finished up with the Sunflower Galaxy: a faint spiral roughly the size of the Milky Way, 27 million light years distant. It was a subtle view after six minutes or so, but still recognizable. 

I had profoundly mixed feelings as I walked home. On the one hand, it continues to amaze me that the EVScope brings nebulae and galaxies within my reach, from downtown DC. On the other - and this can't be stressed enough - using the telescope is not comparable to traditional observing. With a regular telescope, the bulk of your time is spent straining at the eyepiece. You train yourself to see like observers have for centuries - using averted vision, for example - and there's an art to it that you can improve over time. When you're not observing the obviously spectacular - Saturn or the Moon, for example - then what's visible through the eyepiece can be absurdly subtle. The average person would never recognize, let alone appreciate, what you can just barely glimpse. What makes it special is the sensation of seeing with your own eyes what can otherwise be admired only in enhanced pictures. You are truly experiencing the universe, albeit only as well as imperfect optics and a turbulent atmosphere will permit on any given night. 

With the EVScope, by contrast, you navigate an app on your phone. You stare at a screen as the telescope effortlessly targets and then observes your chosen object for you. Slowly, a picture emerges of the object you've selected. It's a little like a picture you can Google - something taken by Hubble, for example - except way worse. As the picture slowly brightens, you wait. You scroll through other stuff on your phone, perhaps, or you sit there thinking. One thing is for sure: most of the time, you aren't actually looking at space at all. Eventually, you turn your attention back to the app and if you're satisfied enough with the picture, you target something else. You end up with pictures that look impressive when they're small, on your phone, but - owing to their resolution or the unavoidable influence of light pollution - underwhelm when you blow them up on your laptop.

It's exciting to find what's out there, in the sky, that you could never see with traditional optics (barring a difficult-to-use astrophotography setup, of course). But sometimes, walking home, the experience leaves you cold. Sometimes, you feel like all you've done is played with screens. You haven't really experienced nature, and you certainly haven't learned an art. Everything was easy, so occasionally it feels like little was gained. You might as well played with a screen at home. 

On some nights, the EVScope can feel like a toy - whereas a more traditional telescope always feels like a tool. Maybe that's because of how and where I'm using the EVScope. Maybe the telescope could do more under a darker sky, and certainly the EVScope comes with citizen science features that I haven't begun to access yet. But with the similarly-priced FC 100DZ, for example, I feel like I'm engaging in an old art with a rich history. With the EVScope, I often feel more like I'm playing a game on my phone. Both have their virtues, but if I had to choose one telescope - it would be the refractor. 

Here in DC, it's hard to avoid thinking obsessively about the demoralizing news from eastern Europe. Yet the skies cleared recently, enough for an hour or two of late-night escapism. A few nights ago, I slipped out with the Takahashi. Transparency was really good but seeing was far worse than average, and since it was well below freezing I didn't want to stay out for long. Still, the FC-100DZ performs so well in poor seeing that I still managed to have a nice view of the waning Moon from my new backyard. 

Conditions were similar last night, with good transparency and poor seeing. By 10 PM the Moon was only just beginning to rise, which means that the sky was still quite dark. The Big Dipper was climbing towards zenith, and that gave me a chance to image Bode's Galaxy - M81 - with the EVScope 2. 

I tried imaging M81 with the EVScope 1 on several occasions last year. I have a particular fascination for barred spiral galaxies like M81, which at 12 million light years away is a little smaller than our galaxy. I'm not sure where that comes from exactly, though the shape is certainly aesthetically pleasing. As a kid, I vividly remember admiring a picture of a barred spiral - was it NGC 1300? - that really captured my imagination. Then I found out, when I was a little older, that our own Milky Way was actually a barred spiral, not the conventional spiral it's usually portrayed to be. That was a fun little eye-opener for me. 

In any case, observing Bode's Galaxy with the EVScope 1 was a disappointment for me. The galactic nucleus is bright enough, but the spiral arms are subtle and easily lost in the downtown DC light pollution. I never got much more than a blurry circle. The EVScope 2 allows me to take longer exposures, however, and that plus its higher resolution made me hopeful of a better outcome last night. 

And indeed, this is far better than anything I managed with the EVScope 1. To capture this 26-minute exposure from my backyard in downtown DC, after just a few seconds of setup time, seemed borderline miraculous to me. This time, I also peered through the new and improved eyepiece of the EVScope 2. What a huge improvement! Looking through the eyepiece of the original EVScope was like looking down through a barrel at a tiny, pixelated square. But the eyepiece of the EVScope 2 feels like . . . well, a proper eyepiece. The view is circular, it feels close, and it's noticeably higher resolution. In fact, it looks more impressive than the image above. 

The gallery above shows the difference between unprocessed 9-minute, 18-minute, and 26-minute exposures. The difference is subtle, but it adds up. Note the relative lack of a diffuse glow around the galaxy. With the EVScope 1, that glow used to creep into my exposures after a few minutes, as a result of light pollution here in DC. That's one reason that my views were so much better out of the city. The EVScope is much better at filtering out light pollution, which makes it a far more capable telescope for deep space observing in the city. 

When I ranked the telescopes I'd owned last September, the EVScope 1 came it at number 7. I'd rank the EVScope 2 a good deal higher - definitely in the top five, maybe even the top three. It's that good. 

Two things have kept me from posting - and observing - these last three months. First: the weather. This has been about the worst stretch of cloudiness and terrible seeing that I can remember in DC. On the rare nights that seemed promising, conditions worsened just as I was about to step outside with my gear. I remember a similar though slightly less atrocious stretch of bad weather last year at around this time, when I was so impatient to see whether my new Takahashi FC-100DZ really provided better views than the Takahashi FC-100DC I had just sold. Now I wonder: is this the start of a new trend, or perhaps a regression to a mean that existed before I started observing whenever I could? 

But second, I bought a home. That turned out to require a lot of work - more than enough to keep me in, even if the nights had been clear. The new place is a condo with a fenced-in backyard. A backyard! It's what I've always dreamed of. Okay, it's small, and it's mostly for the kids. But when my wife saw the yard for the first time, she reported a gap between the trees that "might be good for your telescopes." My heart skipped a beat. Can you ask for anything more from a partner? 

We moved in just two weeks ago. It's been quite cloudy since, but then, last night, the clouds parted, and the forecast called for better than average seeing and transparency. So I woke up at 4 AM, ready to go. I didn't have to go far: whereas I've long had to walk for ten or fifteen minutes to reach a nearby(ish) park, now I just step out the back door. What a thrill! 

Admittedly, the backyard affords only pockets of open sky, nearly all of them facing east-southeast. When the overhanging trees sprout their leaves this spring, most of those pockets will fill up. For now, however, I was thrilled to see Ursa Major, Hercules, and Lyra all hanging overhead. There are some streetlights nearby, but they're not blinding and their light points down at the ground. For a condo backyard, you can't ask for much more. 

I slipped outside with my EVScope 2. That's right: I've upgraded from my first-generation model. The sequel has a higher-resolution sensor that shows more of the sky, along with a much-upgraded eyepiece. Those were exactly the upgrades that I've yearned for, so when I heard about them I had to pounce. The EVScope 2, however, is not exactly cheap. I bought it at about $1000 more than the original, which of course I had to sell to make the purchase remotely possible. 

When I stepped outside, it was -7 degrees Celsius - that's about 19 degrees Fahrenheit. To cover the approximately 30 degree (Celsius) delta between inside and outside temperatures, the EVScope required a good thirty minutes to acclimate. When I tried to capture an image before it had cooled down, it was predictably blurry and unsatisfying. But after the telescope had reached ambient temperature, the view was rock-steady. 

The EVScope 2 seems to align itself even more easily than the original. It honestly takes no more than ten seconds or so, and then it's ready to slew anywhere in the night sky. Objects also appear more consistently centered in my view after the telescope finds them. I'm not sure what accounts for this; is there really something about the EVScope 2 that could be responsible for it? I'm not sure. Maybe I was unlucky with my first unit. But the improvement sure is handy. 

M51 - the Whirlpool Galaxy - is always a favorite target. Last night it was a little close to the balconies above us, which required me to reposition and realign the telescope a few times to get a decent angle. Then, in just six minutes, I got the above picture. I think it's about as good as the image I got in Lewes, Delaware last summer, with the EVScope 1 under far darker skies. I think the new version handles light pollution far better than the original; certainly it seems to take far longer exposures before the image starts brightening around its edges. The amount of detail on M51 is really extraordinary when you consider it took just a few minutes to get that shot in a light polluted, Bortle 7-8 sky. 

As readers of this site will know, I get such a kick out of M57, the Ring Nebula. With a four-inch refractor in DC it is just barely - barely - there, and then only with averted vision. A larger refractor shows more, but not much. The EVScope, of course, makes it so obvious, and so colorful, in just a few minutes. The EVScope 2 provides meaningfully less grainy images; the nebula looks smoother here, and much more true to life. 

As the eastern sky showed its first signs of brightening, I turned to M13, the Hercules Cluster, to close out the night. There's just something about a globular cluster that is always such a thrill for me, and of course the great Hercules cluster most of all. This view did not disappoint: easily the rival, I thought, of what the EVScope 1 revealed under far darker skies. The EVScope 2 seems to more consistently permit longer exposures; I found that my phone frequently lost its connection to the EVScope 1 when my exposures passed ten minutes or so. Maybe that was just my unit, but still: it was nice to easily cruise on to 12 minutes on an object like M13. 

I kept slipping back inside to warm my fingers as the telescope started taking exposures. That's one wonderfully convenient luxury of a backyard. Still, I didn't lose that early morning magic, when all seems still, even in the heart of a city - breathless with anticipation for the rising Sun. There's just nothing quite like that feeling of being outside with a telescope in the hours before dawn, gazing millions of years back in time and space.
