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.
Summer has truly begun in DC when the forecast calls for back-to-back nights with good seeing, and the planets begin to rise high above the horizon. After a very satisfying morning with my Takahashi FC-100DZ, gazing at the southern icecap of Mars, I hauled out my TEC 140 last night and found the same gap in the trees. Once again, there were Mars and Jupiter in the pellucid morning sky, in good (if not exactly great) seeing.
I'd swapped my DM-4 mount for a DM-6, and my carbon fiber tripod for a Berlebach Uni. The heavier ensemble is much more pleasant to use. As I've written in these pages, there's just not beating the mechanical quality of TEC. Every aspect of the 140 is a joy to see and a pleasure to manipulate. The DM-6 and Uni hold the telescope exceptionally well, with virtually no vibrations even when I adjust the buttery-smooth Feathertouch focuser. If I could have just one setup: yes, it would be this.
I've often found an easily noticeable difference at the eyepiece between quality 4- and 5.5-inch refractors. The TEC in particular has given me my finest-ever views of Jupiter and the Moon, with an ethereal, three-dimensional quality and the sensation of texture that I've never had with another telescope.
This morning, however, I was mildly surprised to find that the view resembled what I'd seen the previous morning, using the FC-100DZ. Granted, I could see a star near Mars that I hadn't sighted with the smaller refractor, and the cloud belts of Jupiter definitely showed more detail in moments of steady seeing. At well over 200x, a dark albedo feature on Mars seemed to more clearly extend north from the southern icecap, which of course I could make out clearly.
Yet the difference was, overall, insubstantial. I think amateur astronomers too often exaggerate the importance of equipment in what they can discern at the eyepiece, and too often understate the influence of the atmosphere. In my experience, even subtle atmospheric differences from night to night - and from one part of the sky to the other - can matter more than very substantial differences in equipment (that might make one setup cost many thousands of dollars more than another). It's humbling to know that a $150 telescope - such as the C90 - could outperform an $8000 refractor (such as the TEC 140) on any given night.
I also wonder to what extent nearby streetlights were running interference, softening the view at the eyepiece. Something like that seems to have happened to me before, when my FC-100DC suddenly showed garish chromatic aberration as I observed the Moon under some bright lights.
In any case, several dark markings - barges? - were fleetingly visible in what I took to be the north equatorial and north temperate cloud belts of Jupiter. I was again struck by the pale and almost washed-out view of the planet, where contrast has often seemed so stark with a 5.5-inch refractor. I thought I could make out a very faded Great Red Spot: not much more than a subtle blotch in the planet's southern hemisphere.
After I packed up, I reflected on a recent trip to some astronomical archives, which I consulted to complete my next book, Ripples in the Cosmic Ocean. Among other stops, my travels took me to the archive of the Royal Astronomical Society of Canada, which is tucked away in a little office on the second-story of a nondescript building in Toronto. There's a heap of telescopes in the middle of the archive, and the Society's wonderful archivist explained to me that all of them, in various ways, tell the history of astronomy in Canada. He hopes to mount them in a museum - and indeed I drooled over some fascinating pieces.
One I found particularly striking: a beautifully-preserved little telescope - is it 40, maybe 50mm across? - used by satellite-trackers in Operation Moonwatch, amid the paranoia that accompanied the early Space Age. The mechanical quality really impressed me - the tabletop tripod alone was a diminutive masterpiece - and I wondered what the optics could reveal. I'll bet today's amateurs would pay through the nose for a travel scope like this one.
I visited the archive to look over some astronomical logbooks, and as usual those were a treat. It can be viscerally moving to read over another amateur's drawings and reflections from decades or centuries ago. Our world has changed - and sometimes other worlds have, too - but there's a common thread: the long-dead observer and I both gazed with wonder at something that's far bigger than our fleeting lives. We struggle to put in words what it means for us, as we obsess over equipment and traces of detail in planetary disks.
We are the Universe, conscious of itself - but only briefly.
The planets are rising high above the early morning horizon, and for once the forecast called for good seeing. I slept fitfully until 4:15 AM, nearly convinced myself to fall back asleep, and finally slipped out the back door at 4:45. I soon found that I couldn't see a planet from my backyard, but I did find a spot nearby where a gap in the trees revealed two brilliant planets. They were remarkably close together - not much more than Jupiter and Venus were about a month ago. With the Sun beginning to brighten the morning sky, I set up my Takahashi and targeted the brightest of those planets.
At first, I thought it must be Venus - that's how bright it was - and I assumed the less brilliant, yellowish planet was Jupiter. For a minute or two I thought my finderscope must be misaligned. I kept targeting the brightest planet, and time and again Jupiter showed up in the eyepiece. Finally, it dawned on me - a little later than it might have, had I had more sleep - that in fact the brilliant planet was Jupiter. I was astonished to find that the dimmer - but still very bright - planet was Mars. It's so much brighter now than it was just a month ago - and that, of course, means that it's fast approaching Earth.
I was a little disappointed upon observing Jupiter. Towards the eastern horizon, the seeing was a little worse than I'd expected, and although I could make out many salmon-colored belts, shimmering in the tremulous atmosphere, the planet seemed a little washed out. It lacked the vivid reds and ochres that sometimes create such striking contrast on Jupiter. At just over 200x the Galilean moons were tiny disks, but without obvious differences in color.
Mars, by contrast, was a deeper red than I've normally seen it. For the first time in two years, I made out a polar icecap - this one the southern icecap - and a dark ring around it that was, in the late nineteenth century, widely assumed to be meltwater lake draining off the cap. I could also discern dark streaks shooting up towards the Martian equator. In the nineteenth century, many astronomers - not just Percival Lowell - figured that these were canals and oases channelling polar meltwater towards cultivated fields. That was how the Martians were thought to cling to life on a drying and cooling world.
Mars is my favorite planet to observe when it nears its biannual opposition (and it's free of planet-encircling dust storms). This morning reminded me of the morning of June 9th, 2020, when I observed Mars for the first time through my FC-100DC, as it began to approach Earth that year. That morning, I was stunned to discern the southern icecap for the first time, along with dark albedo features that had never been visible to me before. It excited me to no end to realize how much more could be visible as the planet wheeled closer and closer to Earth that fall.
I have much the same feeling now. I truly can't wait to see what Mars will bring this year. I wonder what I'll be able to glimpse with telescopes that are a little better than those I had in 2020.
We've had plenty of clear skies lately - after a generally rainy spring - but the atmosphere has been so turbulent that I've rarely thought it worthwhile to take out a telescope. This week brought more of the same, but also something unique: a rare, close conjunction of Venus and Jupiter in the early morning sky. With the sky mostly clear, transparency quite good, and seeing a good deal worse than average, I woke up at around 5 AM last night and walked out with my Takahashi.
I wasn't sure where to go. Trees blocked the view of the planets from my backyard. Before our move, I might have walked to the park I like best, but that's 20 minutes away now. By the time I got there I figured the Sun would be too high in the sky - and I'd be painfully sore from carrying everything. I wandered in that general direction all the same, and then noticed a hill I usually pass while taking my kids to the playground. I decided to walk up the hill just in case - and, sure enough, by the time I got to the top I noticed two brilliant beacons just rising into view above the eastern horizon. Jupiter and Venus!
What a difference the new carbon fiber tripod makes! Walking with it is so much easier, and the FC-100DZ is much more stable now. After setting up I plugged in a 24mm Panoptic eyepiece - for a magnification of 33x - and took in the view.
I'm not a big conjunction guy - I care much more about seeing details on other worlds than I do about seeing those worlds appear close together - but it was pretty impressive to see both Jupiter and Venus in the same field of view. Although seeing was very poor and it was hard to make out much detail on either world, it was easy to get a sense of just how different they are from each other, and how diverse even our little Solar System really is. It certainly helped that three of Jupiter's moons were clearly visible, and that Venus was roughly halfway illuminated. I tried to take a customary blurry cellphone picture, and just by chance at that very moment a plane zipped in front of Jupiter.
As night turned to day, I packed up and walked home. When I returned to my backyard, I noticed that Jupiter and Venus were both clearly visible from a little spot near my fence. Maybe I hadn't needed to walk, after all? Still, there's always something magical about that hour before sunrise, when the city is still asleep and the loudest noises are often birdsong.
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.
With a backyard, I'm able to do something I don't think I've ever tried before: observe the Moon before sunset. I just could never imagine doing that in my old home. On my former rooftop, I might have been besieged by my neighbors, and in a nearby park, hounded by dogs. But now, at last, I can relax behind a fence, set up a nice refractor, and enjoy the Moon at my leisure with a beer in hand. It's beautiful.
During my move, I'd noticed that the focuser on my Takahashi FC-100DZ had a little too much give. The culprit, I realized, was a loose screw. Repairing this little issue led me to consider upgrading other aspects of my grab-and-go setup. I parked the telescope inside to attempt to quantify the vibrations I'd long experienced with the Berlebach Report tripod I'd been using. It didn't take me long to realize that, even in a completely wind-free environment, those vibrations were intolerable at high magnifications.
I will still need to walk to the parks I've often frequented - my little backyard only reveals so much, and the pockets of sky I can access will close when the trees regain their leaves - so I started wondering: did I need to sell the DZ for a lighter telescope? I hated the idea, but I certainly don't want to haul around the tripod I use with my TEC 140 just to use a four-inch refractor. Uncharacteristically, I wrote a note asking the CloudyNights community for help, and help I received.
Carbon fibre mounts, some of the responses stressed, could yield fewer vibrations than my wooden mount. This seemed counterintuitive to me - wood, I thought, tends to dampen vibrations - but I went ahead and purchased an Innorel RT90c Carbon Fiber Tripod. I was skeptical, but sure enough: the tripod just about halved the vibrations I'd experienced. It's also much lighter and more compact, meaning that I now have a more portable and more stable grab-and-go setup. Best of all, I get to keep the DZ: a telescope I love.
I took the above picture of the waxing Moon a couple days ago (February 9th), at around 5:00 PM. At the time, seeing was worse than average, but transparency quite good. Note how much lunar detail the FC-100DZ reveal in even poor seeing; it's quite remarkable.
Observing at 5 PM gave me a chance to, at long last, share my passion with my kids. My eldest is 5, my youngest 2. Both insisted that they could see craters, though my daughter claimed that the Delos eyepiece was a little hard to use. And it's true: it takes a little practice to know where exactly you should position your eye with a big, complex eyepiece like that. I wonder whether a simple Plossl eyepiece would be a better bet for the kids - and for outreach more broadly. It's what's I use with my students (admittedly, partly because I don't want to risk my pricier eyepieces).
It clouded over that night, unfortunately, so I wasn't able to observe after sunset. Yet when I stepped outside the next night to get some air, I realized to my surprise that I could see the Moon setting in the west behind my building. Clouds were rushing in, and the temperature was falling fast. Before my move, I would never have observed in those conditions. Yet now it took me all of three minutes to pop inside, grab my Takahashi, and set up everything up in the only corner of my backyard that still afforded a view of the Moon.
Neither the telescope nor my eyepiece had cooled down, and seeing was atrocious: about as bad as it gets in DC. But as the picture reveals, there was still plenty of lunar detail to be seen. The Takahashi excels in good seeing, but I've also found - like others - that it manages to outperform just about any comparable telescope in poor conditions.
I'm hopeful that, in late fall, winter, and early spring, I'll be able to use my backyard to study the Moon far more consistently than I ever have before. In that effort, I suspect the FC-100DZ will be my most important tool.
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.
It's really hard to beat autumn in DC, and I'm trying my best to take advantage of every clear night. When conditions took a turn for the better tonight, I hurried out, Takahashi in hand, to the nearby park. Some kids were playing hide-and-seek nearby with flashlights - not exactly what you want when you're tired from playing with your own small children - but I didn't need dark-adapted eyes. I was out early enough to observe the waxing Moon and nearby Jupiter. I thought I'd already had the year's last glimpse of Jupiter; now I was determined to have one more look.
Jupiter was low enough in the sky to be tinted red by the thickening atmosphere, and in that corner of the sky seeing was mediocre at best. Still: I could clearly make out ruddy Io, just coming out from Jupiter's disk, with its shadow still on the planet. I couldn't believe my luck. I was able to observe such shadow transits for the first time last year, but I never had the chance this year - until the very last night I could view the planet.
The seeing wasn't good enough to reward prolonged study of Jupiter - and, to be honest, my much bigger TEC 140 has spoiled me a little with its more colorful and textured views of the planet. So I turned to the Moon, then illuminated perfectly around my favorite corner of the lunar surface: the area between the giant craters Plato and Copernicus.
Tonight I was especially struck by the length of the shadows in Plato, which are caused by the crater's mountainous rim. The shadows seem to be caused by mountains that must be higher and steeper than any on Earth. No wonder the Moon was widely considered before the Space Age to be a world of soaring mountains with the proportions of stalagmites in caves.
While the rim of Plato is lined with jagged peaks - remarkable, given that they're nearly four billion years old and would be ground to dust on Earth - they rise "only" around two kilometers above the lunar surface. That's far lower, of course, than Earth's tallest mountains. It's the low elevation of the Sun above the surface that casts shadows long enough to extend the entire 100-kilometer width of the crater. Some nineteenth-century astronomers thought those shadows flickered and thereby betrayed the presence of a lunar atmosphere; not the case, of course.
As I was disassembling the telescope, I happened to look up just as a fireball briefly illuminated the sky: a meteor quite possibly older even than Plato. It was a marvelous sight. I'm continually amazed at what you see just with the naked eye, if you take the time to occasionally glance at the night sky.
One last word on equipment. The Takahashi is beautiful and its optical quality is absolutely top notch, of course, but mechanically it is definitely a step below the TEC 140. The focuser and sliding dew shield, in particular, are just not quite as smooth and solid. I don't know that there's anything I'd change about the TEC, but the Takahashi has a few quirks here and there that I might address if given a chance. Still, it's a little powerhouse and once again acquitted itself well tonight.
The sky was that beautiful, robin egg blue yesterday, and sunset faded into an equally clear night. Seeing and transparency were both well above average, so I thought I'd take the TEC 140 out again to have my first look at the Orion Nebula since the spring. Sadly, the hour lost with the daylight saving time adjustment means that the bright planets are now too low in the night sky by the time I can make it out of the house; I'll look for them again in the spring.
By midnight Orion was well above the horizon, with Sirius right behind, climbing up out of the glow of the National Mall. After a few minutes telescope and eyepieces acclimated to the crisp evening air. When they did I took out a 10mm Delos eyepiece, and was delighted to find that I could clearly make out six stars in the Trapezium (Theta-1 Orionis) - the little star cluster at the heart of the Orion Nebula - without using averted vision. I've never been able to see the E and F stars so clearly, and I was especially impressed because they were still emerging from the worst of our DC light pollution.
The green-blue glow of Orion billowed around those stars, of course, with plenty of nebulosity dimly visible (this time with averted vision) even well beyond the brightest arc of the nebula. As usual, the effect was mesmerizing. Under an urban sky, Orion may be the only nebula or galaxy that looks better through one of my refractors than it does through the EVScope. With a 24mm Panoptic eyepiece I could observe just about the entire sheath of Orion's sword, with the nebula at the heart of it - truly a sublime view.
It was getting late by the time I'd had my fill of Orion, so in spite of myself I decided to forego looking at any of the beautiful double stars in the sky right now (except Rigel, an old favorite). Instead I turned to the Andromeda Galaxy, just to remember what it looked like from the city with a truly top-tier refractor. It was a dim blob, of course; no match for what electronically assisted astronomy can reveal. But still, as always a thought-provoking sight.
The march home was painful and exhausting - I had to stop a couple times along the way - but still I was happy to have the season's first view of Orion. Next time with the EVScope, I think.
We've had a few clear nights this week, with seeing and transparency both hovering near average. It's been a demanding month at work, but I had to step out last night, Takahashi in hand, to catch a glimpse of Jupiter and Saturn. The glare of the rising full Moon, however, discouraged me from going to the park near my house - it would just be too bright, I thought - so I popped up to my rooftop for a quick look.
That rooftop really isn't suited for serious observing. Somehow the concrete slabs thrum with vibrations from my building, and the warm air boiling from the rooftop always worsens the seeing, sometimes dramatically. Nevertheless I did steal a few clear, stable glimpses of Jupiter and Saturn: enough to make out countless zones and bands on Jupiter, and the Cassini Division on Saturn. The small, orange disk of volcanic Io, I believe, was just about to move across the Jovian clouds; I've been so overworked lately that I didn't bother to check.
Then I looked over at the Moon, still rising in the east. Like most observers, I always prefer the Moon when it's only partly illuminated - I love the shadows along craters and mountains - and in any case tonight it was clear that the atmosphere along the eastern horizon was just not going to cooperate. Seeing and transparency in that corner of the sky, it seemed, were particularly challenging. Still, the Moon is always - always - a striking sight through a fine refractor, no matter the state of the atmosphere.
