I was out last night with my maksutov catching some lunar views!
The seeing was listed as bad seeing 2/5 transitioning to average seeing 3/5 - mostly clear - mostly transparent - backyard red/white zone- 22:30 to 01:30
With my mak cooling in its bag for hours and the moon higher up now clearing my house, I initially set at one part in the yard, to catch a small observing window until a tree obstructed my view, then I had to move my mount to another location for the duration of the night to view around the tree so to speak.
The views were blinding bright with the 48mm brandon @ 83x mag and 2.4 exit pupil. The seeing wasn't ideal but the Mak was stable and putting up some good views. This eyepiece is perhaps one of, or my favorite all time eyepiece for DSO's and lunar viewing. Razor sharp porthole into space, with long focal length scopes. Can cause blackouts with excessive eye relief but you get use to it.
I spent two hours looking at the disk, 3 hrs total outside ending at 01:30 but I took a 45 min break to go inside and eat.
I usually focusing in on the cratered northern top of the moon. Pythagoras with its central peak was particularly nice. Carpenter, Philolaus C and Anaxagoras were dominating the view.
Another crater that drew me in was Harpalus with its etched rim. As you get closer in from the lunar disk, contrast seems to drop a bit. Not much, but the full moon slightly washes out contrast on the face on features I find, with any scope. That's why I use a 1.25" Lumicon orange filter in smaller scopes, especially when near fully illuminated.
Regardless, my standard for focusing was using Plato and Sinus Iridum. By 01:00 the seeing was starting to stabilize. Now we are talking. Before, after trying the 32, 24, and 16 Brandon's, I found the conditions warranted only the 48.
With the seeing turning into only the slightest of waviness, now the 32 could come out to play and be aesthetically pleasing. Sometimes the 24mm for 166x mag.
With the 32 and sometimes the 48, I could see a feature in plato. I think this is the first for me. Not sure what it was, when I tried to use a higher power it didn't really support it to well. It might have been craterlets B and C , almost seen as one from this far away(with the 48mm @ 83x). Or, it was craterlet A.
I studied the terraced semi-circle rim of Sinus Iridum, moved down to Montes Apenninus. This feature really deserves a terminator, like in the first quarter phase. Contrast wasn't jumping out at me, just identification. Really, the only thing that could have made this night better was being in any phase besides fully illuminated.
I did however observe the ray structures for quite some time. With and without the Lumicon light yellow or the neutral density 25% filters, the ray structures were contrasty and pleasing. Tyco, Kepler and Copernicus showing off in all their glory.
I could see central peaks in 2 out of the 3, none in Kepler.
After this, I packed it and went inside.
Let's hear how your night went. Did you observe the moon? If so, what equipment did you use, what features did you see?
