Fabulous sketch Rich, bold 3D craters, subtle surface shadings, superbly fine detail - an accurate, close-up eye-piece view. Awesome!

Rich,
Excellent description of how this crater pair came to be. This is the finest sketch of Messier and Messier A I have ever seen. Fantastic work.

Rich,
Super observation and the way you render the texture of the mare surface is masterful.

Rich,
Nice job! Makes me want to look for Messier and Messier A next time I observe the Moon. I use a binoviewer, too. Great for lunar work. But Luna must be pretty bright through a 12". Do you use a filter? Which one? I've tried several, but so far I like the #47 Violet best. Not a true natural color view, of course, very easy on the eyes at 3% VLT.

Not only a beautiful sketch, but also an educational post! 
I learned something new today.

Thank you so much Sally, Vincent, Frank, Michael, Mike and Rony!
Mike, I use no filters when observing the Moon (maybe that's why my old eyes are fading! ) Although at powers less than 150X the light is intense, I usually sketch at around 250X or greater which helps to diminish the intensity greatly. This one was done at 305X. I'll look into that #47 Violet filter though, because I sometimes sketch at 80X-150X for those wider synoptic views.

Rich,
An outstanding observation of Messier/Messier A. This is a very interesting pair of lunar craters on the Moon as they appear to have been produced by a low-angle object (asteroid). It is interesting to study this pair under different lighting conditions. Thank you for sharing it with us all.

I have too many floaters to bear looking at the bright expanse of the Moon without a filter, and a binoviewer helps tremendously, also. Without these extras, looking at the Moon at higher power would be torture for me. With any filter, looking at the Moon at high power with anything less than an 8" scope - or maybe at least a 6" - is not a good experience for me. I like the 47 Violet filter because it is so dark, and the violet tinge itself seems to be soothing to my eyes. I've tried other filters, but so far it is the best for me. I'm really surprised no one else - as far as I know - mentions it for lunar observation. I haven't tried my LP and DSO filters yet; they may give interesting and useful effects for the Moon.

Rich,
I have been showing your beautiful sketch to folks with an interest in astronomy that don't sketch down here in Mesa, Az. They are in awe of you skill level (me too). Super excellent!
