I've written about the EVScope and Electronically Assisted Astronomy (EAA) quite frequently in these pages. I was skeptical at first - partly because my EVScope had a technical problem - and only came around slowly. Only last night did I become an enthusiastic supporter.
I stepped out on a warm, breezy night with the EVScope in its backpack. Transparency and seeing were both around average; there was no Moon. When I reached our nearby park, I set up in all of 30 seconds. I decided that my first target would be the Eagle Nebula, which I've never glimpsed through a regular telescope. The galactic core was lost in light pollution over the National Mall - the sky seemed closer to white than black - so I wasn't optimistic.
And yet! When the EVScope found its target - in just a few moments - and started gathering light, a multitude of stars snapped into view, and then the nebula. After a couple minutes, light pollution started to cloud the view - I haven't tried to tinker with the settings that could help me resolve that issue, not yet - so I stopped the exposure after eight minutes or so. I was left with this:
In the dark, on my phone, it looked spectacular. Look! There are the pillars of creation - star-making factories so memorably imaged by the Hubble Space Telescope - somehow visible from downtown Washington, DC, just nine or so minutes after setting up in an urban park. This image does it for me - I like my nebulae ghostly and ethereal - but with a little image processing, even more detail pops out (see the picture at the beginning of this post).
Now it was on to the Trifid Nebula nearby, it too lost in downtown pollution. Not for long! Again, I'd never seen it with a regular telescope, yet again, it didn't take long to pop into view through the EVScope. This image I like a little less; the unprocessed version doesn't quite bring out the blue. Still, getting this detail so easily in the middle of a city feels nothing short of miraculous.
Then it was off to the Ring Nebula which, of course, never fails to impress - albeit in very different ways through an optical or EAA telescope. Whether because of a software update or an unusually transparent sky - I suspect the former - I was, for the first time, able to see the white dwarf at the heart of the nebula. Seeing that would require an enormous regular telescope - too big for my car - and a very dark sky. Imagine my wonder at glimpsing the dead star from the city: our Sun's future, five billion years from now.
I didn't have much time left, but I wanted to see how far I could reach. I turned to NGC 5907, a galaxy marginally larger than our own, around 54 million light years distant. I could only take a short exposure - I really did have to leave - but there: an edge-on spiral galaxy that I would never have been able to observe even with my TEC 140. The light in this picture left its source not only after the dinosaurs went extinct. What a thought!
I packed up just as quickly as I set up, and then a pleasant walk home with my backpack. It is simply remarkable to see so much so easily. I've often seen the EVScope's hardware discussed and praised, yet what really stands out to me is the software. If only other mounts, carrying regular telescopes, were so easy to use.
It seems that the cloudy, turbulent days of winter - in more ways than one - are finally coming to an end. In the wee hours of March 20th, the sky was clear, transparency was (supposed to be) high, and seeing was about average. Conditions, in other words, were about as good as we've had in months.
I trotted out with my EVScope, intent on imaging some of the deep space wonders that are now prominent in the early modern sky. After a lightning-quick setup, as usual, I directed my attention to M51, the Whirlpool Galaxy, which is colliding with (and ripping apart) NGC 5195, a smaller galaxy. After a seven-minute exposure, the results impressed me - and for once I noticed that the image looked better when I peered through the eyepiece.
Two other galaxies beckoned around the same constellation (Ursa Major, or the Big Dipper): Bode's Galaxy (M81) and the Pinwheel Galaxy (M101). Both are much trickier targets. Bode's bright core is easy to find, but its spiral arms are easily lost; the Pinwheel is big, but has generally low surface brightness. While transparency was supposed to be high, the sky was actually remarkably bright, and I noticed clear halos around street lamps. If anything conditions promised to be poor for both galaxies, and sure enough I wasn't pleased with the results. Here's a three-minute exposure of the Pinwheel Galaxy; you'll see it doesn't exactly impress.
That's the thing with the EVScope, and something I haven't seen mentioned in any review: like all telescopes, it performs much better under a dark sky. While there's a lot of hype about how it will reveal deep space objects in the middle of the city, that promise holds up much better for objects that are already bright. Fainter objects can be lost in the glare of light pollution, just as they are in traditional optical telescopes. I'll try these galaxies again when conditions are better, but I don't expect radically different results.
By the evening of the 20th conditions had improved dramatically. Both seeing and transparency were now good: a confluence we haven't had here in DC since November, maybe October. Although I was exhausted from waking up early on the previous night, I had to walk out with my Takahashi to catch the Moon while it was still quite high in the sky.
As I've written, I've been a little disappointed since swapping my FC-100DC for the DZ, which is supposed to offer slightly better color correction. While I had only used it in nights of bad seeing, I was beginning to worry that it might have been knocked out of collimation in transport. After I set up on the night of the 20th and glanced at the Moon, those worries only grew: the image looks distressingly soft, and I started thinking about how to contact Takahashi.
Yet after a few minutes the telescope cooled down, and then: wow. Suddenly the Moon snapped into crystal clear, razor-sharp focus, with absolutely zero false color anywhere - including along the lunar limb, where the slightest undulations and shadows were totally crisp. No matter which eyepiece I used, the detail was spectacular. What stood out the most? Probably the rilles; they seemed to be everywhere, and so delicate that they looked like veins on a living thing.
After a little while I concluded that the view seemed best with my 6mm Delos at 133x. At that magnification I could still see the entire Moon, but I was close enough to make out truly breathtaking detail, in every conceivable shape and form. It truly felt as though I was looking out the window of a spaceship, approaching the Moon after a long journey from Earth.
There are times when the atmosphere cooperates, and something spectacular is in the night sky, that it doesn't take long for me to have my fill; to feel as though I can't take in any more, because I just want to savor and remember what I've seen. So it was this night. After about 40 minutes, I packed up and walked home.
So yes, the FC-100DZ is an extraordinary telescope. To me, it has a bit less false color than the DC and significantly less than the TV-85, although both of those telescopes really had very little, and that gives it a small edge in sharpness. The difference is subtle but noticeable - on nights of good seeing. Of course, those night don't come along very often, and I've found that on most clear nights the state of the atmosphere matters far more than slight improvements in instrumentation. The FC-100DZ's bigger improvement over the DC, as I've written, is probably its modest but meaningful mechanical upgrades.
Still, owing fine refractors has made me a little obsessive about the details, and for me the move from a DC to a DZ appears to have been worth it. That's a relief!
On November 16th, the sky was clear and, after a glorious sunset, atmospheric seeing promised to be mediocre but transparency was predicted to be superb. With no Moon in the sky, conditions were right to take the EVScope for another spin.
I've now (separately) purchased the backpack that's sold with the EVScope; my rolling case, I suspect, my knock the telescope out of alignment. When I set it up this time, collimation was just about perfect. I made a couple tiny tweaks - again, this took seconds - and then rapidly achieved fine focus with the built-in Bahtinov mask. It was cold and I was exhausted, so I figured I would only take two ten-minute exposures of the Andromeda and Triangulum galaxies.
Moments after the telescope slewed to Andromeda, I heard some rustling in the distance and noticed a dim orange glow, appearing and disappearing. Then the sounds of muttering wafted over on the breeze. It seemed I was sharing my park - and I had the disquieting feeling that I was being observed. After about eight minutes or so, I thought a third shadow joined the two in the distance, and then the rustling got closer. The conversation, it seemed, was definitely in Russian. Suddenly a flashlight turned on; there were three people, and they were walking directly towards me. I greeted them: "Hello? Hi!". At that, one of them exclaimed "oh my God!", and then all three of them darted to the side, behind a bush, and disappeared. The sounds receded into the distance.
That was unsettling. Fortunately, after ten minutes the Andromeda exposure turned out nicely, considering the light pollution. Collimation and fine alignment really makes for much tighter stars and far better images, though I imagine things would be better still in superior seeing (and, of course, under a darker sky).
Now it was on to Triangulum. It wasn't long ago that I managed to spot the galaxy with the FC-100DC, under darker skies some distance from DC. I noticed only a slight brightening of the sky, with averted vision, in what I could just perceive - or imagine - to be a spiral pattern. Clearly observing the galaxy now, from downtown, is a particular thrill. I don't know why, but Triangulum in particular has always captured my imagination. Maybe it's because it gets so little attention compared to the two giants of our Local Group of galaxies, or maybe because it's a face-on galaxy with distinctly knotted spiral arms . . . I'm not sure why, exactly. In any case, I find that the EVScope does a particularly good job on this galaxy (see above).
And again, during the exposure I was in for a shock. With a loud thump and a lot of growing, a rabbit suddenly rushed right by the telescope, a fox in hot pursuit. The fox stopped short of my location with a snarl, then scampered - its little legs a blur - over a hill and behind a bush. Both fox and rabbit were no more than six feet from me. I couldn't wait to tell my four-year-old daughter in the morning.
Anyway, after a few more minutes the Triangulum exposure was done to my satisfaction. I packed up the telescope, warmed my chilled fingers, and walked home. Suffice it to say, I've really started to enjoy the EVScope.
A few days after my strange night with the EVScope, an ad appeared on AstroMart that forced me into hours of tortured thought (usually while attempting to get my one-year-old to sleep). Here was a Takahashi FC-100DZ, used only once and in pristine condition. As I've mentioned before, this year I've been tempted to swap my 100DC for a DZ. The DZ has better color correction and its optics might be marginally sharper, on average, though both improvements may be difficult to detect visually (I read many opinions, and they seem to differ). You can read a great breakdown of the relative merits of the four current FC-100 models here.
I've resisted the urge to swap the DC for the DZ because, first, the hassle and expense seemed daunting, and second, the DC's weight is supposed to be lighter. The difference in weight, I concluded, outweighed (sorry) the marginal difference in optical quality. Yet the four-inch refractor is my most used telescope, and now I couldn't resist the urge to upgrade to maybe the finest refractor of this size ever made.
So, I bought the DZ and sold my DC (along with some other stuff to make up the cost).
I have to say, the comparison between DC and DZ surprised me in a few ways that aren't covered elsewhere. First and for my purposes most importantly, the weight difference between the two telescopes is scarcely noticeable. In the above pictures, you can see the DZ in a configuration for short-range, daytime viewing. However, to reach focus for astronomical viewing you must detach one of the couplings, and that makes the DZ noticeably lighter. It is then also more compact than the DZ when the sliding dew shield is tucked over the optical tube.
Second, the most important couplings of the DZ do not screw apart but rather use thumbscrews and compression rings. You can also use that system to attach a diagonal, and I can't tell you what a difference it makes. I actually detest the Takahashi fetish for stacking screwable couplings in the visual back. The couplings, I've found, tend to stick together, and they're not wide enough to grip easily. It's easy to damage them (cosmetically) by applying too much pressure (I did as much to one of the DC's couplings). The new system brings the DZ in line with most other fine refractors, and it is just such a relief.
Third, to balance the telescope - using just about any eyepiece - the clamshell tube holder must sit farther from the visual back than it does with the DC. This may seem like a very minor detail, but it provides more room for a red dot finder (RDF) just in front of the visual back. My Rigel QuikFinder RDF is now in a more comfortable position, and it's those little details that can make a real difference in the field.
Fourth, the focuser is just a bit nice. Its knobs are metal - not plastic, as in the DC - and the feel is a bit smoother (though I did need to adjust the tension knob for my big Delos eyepieces). I sold Takahashi's two-speed focuser upgrade with the DC, and although I will no doubt miss the fine focus on the DZ, I didn't like how the two-speed add-on left some daylight around the gear housing. On the DZ, I'll stick with the stock focuser. That focuser, by the way, allows me to reach focus with all my eyepieces - something that was just out of reach for the DC.
Finally, although the sliding dew shield is very smooth and easy to use, its tightening screw does leave a subtle mark on the optical tube that is noticeable when the dew shied is deployed. I wonder if the previous owner tightened the screw a bit too much, but I doubt it; I think this is just a natural consequence of the technology. It only matters if you're obsessive about the condition of your equipment - but Takahashi telescopes are so beautiful that they tend to bring out that obsession.
Last night, and against my better judgement, I took out the DZ for the first time. I say "against my better judgement" because transparency was mediocre and seeing was poor. It's a recipe for disappointment to take out a new telescope in such conditions. I couldn't resist, but I did set up near the cathedral, closer to my house so I could hurry back if observing disappointed.
And did it? Well, a look at Mars did clearly reveal that the atmosphere would not be my friend tonight. And yet, I could plainly make out no fewer than three large dark albedo markings, along with that brilliant south polar icecap. Turning elsewhere, Rigel A and B were laughably easy to split in the poor seeing, and Orion was beautiful even before it emerged from the light pollution near the horizon.
So could I make out an optical difference between the DC and DZ? Not after one night of poor seeing. Mars did seem a bit yellower than it does through the DC, and certainly I could detect absolutely no hint of false color in or out of focus. I'm excited to study the Moon, for example, on a really good night. Yet I don't expect a large or even a plainly noticeable difference. I bought the DZ primarily so I could be absolutely sure that the optical quality of my most-used telescope would never hold back my observations - and so that I would never wonder what something would look like with a slightly better telescope of the same design. It's a tiny thing, but after a while tiny things start to matter a whole lot in amateur astronomy.
It was a cold, damp night when I stepped out with the EVscope and found a relatively mud-free corner to set up in my park. I decided to try my hand at collimating the telescope to see if that might tighten the stars in my pictures, and I hoped to decide, once and for all, whether to keep the telescope before my refund period ran out.
To my surprise, the telescope was badly out of focus when I turned it on - so out of focus that its auto-alignment failed. Fortunately, it comes with a bahtinov mask cleverly built into the dew shield. Achieving rough focus, and then fine focus with the mask, takes a matter of seconds. With that done, the telescope immediately found alignment, and I got it to slew to Bellatrix, a fairly bright star in Orion. Now I turned the focuser knob until a dark cross appeared in front of the suddenly bloated star: the spider vanes holding up what would be a secondary mirror in most reflectors (but is a sensor in the EVScope).
The cross was badly askew, which means that the telescope was poorly collimated. It took all of 30 seconds or so to fix the problem, and even less time to achieve fine focus again. And then, voila: the stars were more closely to dots - rather than smeared blobs - and the resolution of the telescope suddenly seemed higher. Funny how that works.
I tried my hand at imaging a few objects: the Orion Nebula, of course, and the Flame Nebula, Bode's Galaxy, and the little galaxy NGC 1637. The latter was a bust: it's very small, and lost in the glow of light pollution to the south. An unavoidable problem for me is that the EVScope amplifies both the light of deep space objects and the light pollution in our DC skies. It's not a problem for brilliant objects like the Orion Nebula or the Andromeda Galaxy, but dim, diffuse objects are another story. I also didn't take exposures longer than five minutes. It's one thing to gawk at the Moon or Mars for that long - or much longer - but another thing to sit silently in the cold, waiting.
But was it ever cool to see the spiral arms of Bode's Galaxy, slowly brightening on my screen as the minutes and seconds ticked by. Here were photons 12 million years old, from a galaxy nearly the size of our own, somehow visible in an urban sky. The view was quite sharp, I thought, and the telescope performed perfectly, immediately slewing to whatever I asked it to find.
Do I prefer my optical telescopes? Yes, for most objects I do, but it's simply true that the EVScope shows me hundreds of nebulae and galaxies that I never imagined seeing from the city, and reveals glorious detail in wonders I thought I already knew well. It's a keeper. Now if only I could get a lightweight, go-to mount for my refractors . . . .
We've enjoyed maybe the best stretch of clear nights with good seeing that I've experienced since moving to Washington, DC, and I was out nearly every night with a telescope in hand. Between work, childcare, and observing, I had no chance to update this blog - but now it's raining, and I have an hour (but just an hour) to relax.
Roughly two weeks ago, I spotted a Takahashi FS-102 for sale on Astromart. Amateur astronomers will know that this is a four-inch refractor with a well-earned reputation for exceptional optics. It's been replaced by the Takahashi FC-100 series, and I already own a telescope in that line. But the FS-102, while much bulkier than my 100DC, does better at longer wavelengths. And in Mars-watching season, that's what I convinced myself I needed.
Although the FS-102 was supposedly in pristine condition, when it arrived I was dismayed to discover that the lens cell was loose and the tube was covered - I mean covered - with scratches. Luckily, the owner was mortified when I informed him, and I received a (nearly) full refund. I now had some cash to spare, and at just that moment a new copy of Sky and Telescope arrived. A favorable review of the EVScope convinced me to give that telescope another chance (see a previous entry for my first impressions). Maybe the buggy version I owned before had unfairly soured me on the product? It did, after all, offer me a chance to observe nebulae and galaxies I would otherwise never have a chance to see from the city . . . .
After it arrived, I bundled the telescope into a suitcase and rolled it along to my nearby park. After I turned it on, it just about instantly figured out where it was and slewed (quietly) to any object in the sky, like magic. Clearly, I'd been sold a glitchy version the first time around. This was more like it! And when I tapped on "enhanced vision" (I describe the technology in a previous entry), the effect was really satisfying. After a couple minutes gathering light on the Andromeda Galaxy, for example, dust lanes I'd previously spotted only with averted vision clearly snapped into focus.
So, how good are the views? Well: although I managed to achieve fine focus, I think I'll need to collimate the telescope when I'm next out. Stars are not exactly pinpoints, as these images attest, and that's also caused by a tendency of the telescope to move too much while it's gathering and stacking images. There's more noise in the pictures than I'd prefer, and after getting used to my wonderful TeleVue eyepieces, the view through the EVScope's "eyepiece" is really cramped. It's like looking through a tunnel. More importantly: no, seeing an image through a grainy screen is just not at all the same as seeing it through an optical eyepiece. An optical telescope feels like an extension of the eye; not so the digital EVScope.
But damn, it's cool to see galaxies shimmer into view on my iPhone screen. It's simply true that I can see things now that I never would have imagined seeing before, and isn't that what this is all about?
I mean, the Triangulum Galaxy from an urban sky . . . are you kidding me?
I'm still learning how to use this technology, and pictures I've seen online tell me there's plenty of room for improvement. Still, I've noticed that the images look much more spectacular in the app, while I'm in the field, than they do after I get home. Certainly they pale in comparison to even half-decent astrophotographs made with dedicated gear. Now does the technology always work seamlessly. Just a couple nights ago, I had to restart the telescope and reinstall the software before I could get the enhanced vision mode to work, and by then I'd already shivered outside for about 30 minutes. Some objects also look immeasurably better through my optical telescopes. The EVScope is just about useless for lunar and planetary views, and stars look like ugly blobs compared to the beautiful diamonds they resemble through my refractor.
Yet what the EVScope does so well is find that sweet spot between visual observation and astrophotography, and it does so in an integrated package that's usually a pleasure to use. No, I never had the thrill of seeing something with my own eyes - the thrill I've described often in these pages - but I certainly did get a deep sense of pleasure when I glimpsed the Whirlpool Galaxy from the city.
One virtue of the EVScope is its weight. If I stuff the EVScope into the suitcase I used for the APM - which, admittedly, does seem to mess with its collimation - then I can easily sling my Takahashi 60Q over my shoulder (and wedge its tripod in the suitcase). I've now used the 60Q twice, including once in the early morning, with the EVScope gathering Orion's light. I have to say: I was more than a little stunned by its quality. To my astonishment, the Moon through the 60Q really didn't look any dimmer than it does through the TV 85, and details were equally sharp.
Here are three images I took of the Moon over the last week, with the 60Q, the FC-100DC, and the APM 140. A reminder: the 60Q has an aperture of about 2.5 inches; the 100DC of 4 inches, and the APM of 5.5 inches (these are big differences for refractors). The optical quality of each telescope is roughly similar, though I'd say the APM shows the most false color, and the 60Q the least.
That's the 60Q on the left, and the APM on the right. The comparison isn't quite fair; seeing and transparency differed on each night - it was average when I used the APM, and decidedly better than average when I used the 60Q and 100DC - and while the smaller telescopes had fully cooled down when I took these images, the APM in my judgement had not. Still, it amazes me how slight the differences are. I have a new phone, by the way, with a much better camera, and I think it shows.
These pictures were taken after the APM had fully acclimated, and I think it's fair to say that now the aperture difference is more easily visible. There's a deeper and more richly textured quality to these images than there is to the 60Q closeup above. Yet it always takes me aback to realize that, when telescopes are of similar quality, differences from night to night on bright objects - the Moon especially - owe more to atmospheric conditions than anything else, including aperture. It's different for dimmer objects. I can usually see at least five stars in the Trapezium using the APM, for example, but I've rarely if ever confidently spotted a fifth with any other refractor.
Mars was full of detail when I observed it with the APM - wow that south polar cap looks bright and sharply defined right now - but I found that it, and every other bright object, was surrounded by a bright halo that night. This seems to be a common and very annoying optical effect in the skies of Washington, DC. On two nights with the 100DC, however, I had no such problem. Dark albedo markings were wonderfully detailed, and I spent easily an hour both nights just enjoying the view. It's a little sad to think that every night brings us a little farther from the red planet, but the view should dazzle for months to come.
One last note. My first night with the 100DC over these past two weeks was November 3rd. I suddenly resolved to stop doom scrolling and instead do something that distracted me. But what a sinking feeling I felt, walking bewildered to the field, with panicked screams - yes, screams - echoing around me. I walked out on the 4th, too, and the mood was lighter. Then, on the 7th, while playing with my kids in the very spot I usually set up my telescopes, came the good news: the networks had called it for Biden. I'll never forget the scenes of spontaneous joy on the streets: the bells ringing, cars honking, crowds cheering. We may be in for some very dark months this winter, but that was a moment I'll long remember.
This weekend, we travelled to the Shenandoah Mountains with our "bubble family" for a much-needed getaway from Washington, DC. It took a little negotiation - even a short trip with kids requires a lot of luggage - but I eventually received authorization to stow a telescope in the trunk. There wasn't much room, so the telescope had to be small, and that left two options: the TV 85 or the Takahashi FC-100DC. I decided I wanted the extra reach of the Takahashi, so I unscrewed its focal extender - shortening and lightening it - and then found a way to make it fit with my lightest tripod.
To my delight, our cottage turned out to have two balconies, both isolated from surrounding houses, and was just enough of a clearing in the trees to reveal a part of the night sky. That part, I soon realized, could not have been better placed: it would reveal the Ring Nebula and the Hercules Globular Cluster in the evening, and the Andromeda and Triangulum galaxies in the morning. Even better: the forecast called for clear skies on both nights we were there. What are the odds?
On the first night, I stepped directly from my bedroom to the cottage's narrow, second-floor balcony. The air was alive with the squawking of birds and the buzzing of bugs. Luckily I brought plenty of mosquito repellant - although it was hard to forget about the legions of spiders spinning webs just overhead - and wow: what a night sky! Bortle 4, by one classification scheme; yellow or maybe green by another. It was, admittedly, not perfectly dark, but to this city slicker it was nothing short of a revelation. It's been so long since I've seen the Milky Way - but there it was, clearly visible. There were in fact so many stars that it was hard, for a moment, to pick out the constellations! Oh, what I've been missing in DC.
To my surprise, Jupiter and Saturn both turned out to be high enough to view from the upstairs balcony. Saturn was beautiful, but I've had better views from the city. Jupiter, by contrast, was so clear and full of contrast - and, lucky me, I had tuned in just on time to see another shadow transit! To think that I'd never seen one before this month. Callisto, it turned out, had just finished traversing the planet, and its shadow was still in the clouds. The shadow seemed a bit more distinct - a bit more clearly round - than it had been on the surface of Jupiter with the APM 140 on the 10th, but I found I couldn't increase the magnification beyond 123x without the view breaking down. To my surprise, I also found that a new Delos 6mm eyepiece presented a clearly better view than my trusty Nagler 3-6mm zoom.
Next, it was off to deep space. It has literally been decades since I had a telescope under a reasonably dark sky, and so it was such a pleasure to simply trawl through the Milky Way at low magnification, admiring the knots and clusters of random stars. Every patch of the galaxy, every view, resembled an open cluster from urban skies. Incredible.
There are, I realized, deep space objects that look better under dark skies - that is, more of the same - and those that look different. The Ring Nebula, I realized when I finally look that way, mostly looks better. I could easily make out a ring without using averted vision, which I can't do with anything smaller than the APM 140 in DC. Yet I could also make out subtle nebulosity within the ring - a first for me - and the ring didn't look quite as round as it seems in the city. The Hercules Cluster, however, looked completely different: less a fuzzy ball and more an explosion of innumerable stars, textured and complex right down towards the center of the cluster. When I saw textured, I mean it was almost as though someone had sprinkled especially dense clumps of glitter haphazardly over a page already covered with a thinner dusting. An unforgettable sight.
On the following night, I decided to sneak out in the morning, this time on the bigger, first-floor balcony so I could see more of the sky. I never have much time with how little my son sleeps, but I hoped to get a good view of two huge deep space objects whose surface brightness is just too low for urban skies - the Andromeda and Triangulum galaxies - before catching a glimpse of Mars.
Andromeda was impressive: a bright, fuzzy nucleus (of course) and a subtle but immense disk, stretching out of view even at 25x. I thought that maybe - just maybe - I could make out a dust lane after around 15 minutes of peering, but that might have been my imagination. At last I tore myself away from the view and started scanning for the Triangulum Galaxy, which I've never managed to spot before. After about 15 minutes I tracked it down, and wow - was it ever subtle. I could make out its pinwheel shape using averted vision, and that was incredibly special to me.
At last, Mars became impossible to ignore. Snapping in the 6mm Delos I was treated to an absolutely spectacular view of the planet at 123x, featuring that southern ice cap, of course, surrounded by a ring of remarkably dark dunes, and the unmistakable peninsula of Syrtis Major Planum. I have never had such a detailed view of Syrtis Major, and what timing: the Perseverance rover will soon blast off to land at Jezero crater on the border of the region. To be honest, this view alone exceeded my wildest hopes for the Mars opposition of 2020. Amazing to think that the planet will only seem bigger over the next few months!
Yet just as on the previous night, although the view was full of contrast at 123x it broke down when I pushed the magnification much further. I had high hopes for 185x with the Nagler Zoom, but no dice. After a while, it was time to pack up. I was sorely tempted to look at the Pleiades, then just wheeling into view, but I had to be ready in case my son woke up. I couldn't complain, of course; together, both nights were nothing short of unforgettable. I now know: there's nothing better than a fine telescope under dark skies.
With regards to the rest of my setup, I was really impressed with a new purchase: that 6mm Delos eyepiece. Beautiful contrast, incredibly easy on the eyes, and a nice field of view. The 30mm TeleVue Plössl was less impressive - actually, it's long been my least favorite eyepiece in my Plössl collection. Stars seem a little stretched out away from the center of the eyepiece; at first, it's like they're not quite in focus, and then, towards the edge of the view, they stretch out into miniature arcs. I think I might need another kind of eyepiece for beautiful wide-field views under dark skies.
All in all, a memorable trip, and a welcome relief from these COVID times.
