Crater Drygalski is number 94 in the Lunar 100, so a very difficult object (the list is from easy to difficult). But when libration is cooperating, it isn't difficult to see at all. The crater, at the moon edge, was easy to sketch. Love the central mountains: only visible as two small lines. But I had a hard time sketching the hills and brightly lit craters at the foreground.

Jef, 

 

Excellent sketch of Drygalski crater in the libration zone.

You also captured M5, M4 and M3. far right in your sketch

and looks like M14, M15 and M16 in front of Drygalski

You should help me with these ones. I guess they are not Messier objects lol.gif

Hello Jef,

Drygalski looks to be a fine limb crater and you have captured it impressively! Thanks for sharing this one with us!

Clear skies!

Wonderful capture of this elusive crater, well, the far wall anyways! My wife and I were both out in the observatory the same night listening to John Print songs and living in the moment. I was going to sketch the area too, but your sketch took me back to that moment. Thank you for sharing!

stay safe,

Mark

Well done Jef, I feel I am in the LEM looking through the small window when looking at your sketch.

Thank you to you and Frank who remind me the M classification near the limb.

Michel

This made me very curious. I did some research. Correct me if I'm wrong.

- The M is an unofficial designation for mountainpeaks at the southpole.

- The are also called the Leibnitz Mountains.

- They make the rim of the South Pole - Aitken basin (what Wood calls the "BBB: big back-side basin").

- I sketched - without knowing it - (a part) of Lunar 100 object number 96: Leibnitz Mountains grin.gif

It counts to look which area is in a favourable Libration. I do so every time I look at the moon, but missed Drygalski until now. Great sketch.
