The other night I went hiking in a hill outside the great dome of light. I took my beloved 20x70.
The SQM-L reading at the zenith was 19.9. Nothing spectacular, but in that sky I can see the main stars of Ursa Minor with direct vision. In other words, a real luxury for an urbanite.
The subtitle of this report could be: "Spring time: smudges and doubles."
I started with Kemble cascade. It's gorgeous, and although it was within the FOV, I prefer a field of view of 4⁰. In NGC 1502, I can make out 11-12 stars, including the two bright ones (A and E) in STF 485 (7.0-7.1/18"). A beautiful image.
Starting from Epsilon virginis, I head to M53 and then to M64, a galaxy whose shape and orientation I can recognize. I also catch a few more galaxies in the area: M87, M89, M58, M84, and M86.
From Algorab (Corvus), a magnificent double star (2.97-8.47/24"), I head towards Sombrero. Along the way, two well-known asterisms are no less attractive. The first is a small triangle within a larger triangle (I couldn't make out the fainter star in the inner triangle). The second is the famous arrow pointing to the galaxy. With the 10" dob/BV, these two asterisms are even more impressive, by the way.
M44 fills the FOV and is luminously impressive. I stayed with it for a while. M67, on the other hand (and in contrast), doesn't look like much. Don't be fooled: in a darker and transparent sky and if you can add 10-15x (BT) the image is gorgeous (more with more aperture).
I try, but I can't see NGC 2419. A GC that requires darker skies. I can, however, make out NGC 2419/C9. As is often the case with binoculars, the journey is often more interesting than the destination. I find two beautiful doubles: HD65448 (6.1-7.5/51") and HD61907 (7.8-7.8/14").
From Zaniah I head towards M61 (one more smudge in the bag). I linger there for a bit and find another nice double: HD106976 (6.5-6.9/20").
I visit the famous T Corona Borealis to check that it hasn't exploded yet. M~10.1.
NGC 2903 is easily visible, and I can distinguish its shape and orientation. I don't see the elusive NGC 3628 of the Leo triplet. In the same constellation, I enjoy the beautiful starfields of two more doubles: 83 (6.5-7.5/29") and Tau (4.9-7.5/88").
M81/82, after so much smudge, resembles two cosmic lighthouses. Of the two brighter companion galaxies, I think I could occasionally make out NGC 3077, but I'm not sure.
It's already late (I've been observing for almost four hours), but Lyra and Cygnus are climbing a little further into the great dome of light. I can't resist the temptation and I immerse myself in them for a few more minutes. Then I crawl into my sleeping bag and drift off into sleep, immersed in that area of sky I've gladly decided to ignore: the zenith and its surroundings.
