the bright Moon and the fairly good skies have been a good reason to spend an observing session with the Moon.
After watching the terminator,
I have been spending most of the time in the Gassendi, and in the area around,
It has been fascinating to see numerous rimae in Gassendi, and the Rupes Liebig in Mare Humorum, and other rimae on the rim of Mare Humorum.
The annotated panel is here,

I don't suffer from insanity. I'm enjoying every minute of it.
A great place to spend time on the lunar surface, glad you managed time to enjoy it.

It looks like there is not too much wrong with the optics of the 150 f5 Achro, or the Docter eyepiece! Although I am not sure what you mean by "speed 3.5"?
Keep up the good work.
All the best,

Thanks JG! Great images for hand-held.

Thank you Dean, and thanks to all, for the kind words!
The 3.5 has been the speed of the lens adjustment (f-stop) on the camera behind the eyepiece, when afocal imaging.
Optimally, the camera lens speed (f-stop) should be adjusted much slower, but with the camera hand held, the resulting exposure time would be too long for the camera O.I.S.
Back to the documentary pics.
Next to Aristarchus there is a rectangular Dog Poo (Hundescheisse) with two small craterlets, which have been nicely resolved through the eyepiece. The Cobra has been still in the shadow.
Clear skies,
JG

Nice session JG; I'm envious! Your pictures and descriptions are excellent as well.
Nicely done; hope your skies continue to be clear!

"Hundescheisse" - I love it! German can be very descriptive- this is exactly the word you need when you are cleaning up the mess while trying to hold your nose! I said something very similar this morning after one of our cats chucked on our nice clean quilt cover...

it is all about the seeing and long cooldown of the telescope and of the eyepieces.
On the side of optics, some eyepieces are doing better on the 6" F/5 achro, and lots of the others have been simply the wrong choice, even if highly regarded by the reviewers on some other forums.
The old Tak 5mm Abbe has a very good match to my 6" F/5 achro, and maybe the 7mm is good as well.
Clear skies,
JG

Hello JG. I am glad that you got this night to enjoy the wonders of the lunar beauty. And, I enjoyed your report and images, including the nice annotated version. Thanks for sharing this work with us on hereJG, and I hope that you have another opportunity to delve back into to the great surface details of our moon again soon.
