Just ran across both of these and decided to post them. I was studying albedo and found it an interesting aspect of lunar observation.

I've got to add this to the calendar I compiling!
Great work - makes me want to survey the limb again.

The albedo sketches resulted from checking contrast after removing my secondary baffle. And the Paw, of course, inspired by you was just putting on a show that night. The other two craters are Aldrin (bottom, I think) and Collins (would be at top.)
Anyway, that limb sketch shows just how difficult lunar sketching is. It's best left to the professionals.

Very nice sketching but be careful, you are going to get hooked and you'll begin missing Jupiter, Saturn and Mars opportunities. ~~~~ alright, alright just kidding.
The Moon is a great target for sketching practice when looking for a challenge.

Thank you, Ken. Again, these sketches came about as a result of albedo and contrast study, not out of any innate talent.

It is a nice sketch.

Of the three, I find the third most interesting. I like the way you've done the depth of the scene toward the horizon.

Knucklehead, yea, Cat's Paw is very near the Apollo 11 landing site, hence the two prominent craters (right) Collins (top) and Aldrin (bottom) in the sketch. Armstrong is out of the sketch (toward the top.) The Paw is the rather shallow (lower contrast floor), wider crater above the two elongated ones...one of which is Sabine C (right, I believe.) So, we're in the vicinity of Sabine. It's pretty smallish at 1.6 miles across. It took exceptional seeing in a 6" aperture. Pete inspired a look at this one.
