Both of these craters look similar when their floors are in shadow as was the case when I viewed them. Lansberg (40 km) is a walled plain crater sitting where Mare Insularum meets south Imbrium. This old impact dates back to the Upper Imbrian and is near the center of my sketch. Reinhold (49 km) is a prominent lunar impact crater of the Eratosthenian period and is also on Mare Insularum. It is below Lansberg near the bottom center of the sketch which by direction is north as per the inverted Newtonian telescope view. At the top of the sketch (south) I was able to catch the Riphaeus Mountains receiving first light during this waxing gibbous phase.

Ian and Michael,

Thank you both for your nice words and comments.
As the weather gets colder and clouder here sketching opportunities tend to decrease until Spring.

Michael, I went over to your gallery after clicking on your name above your Avatar. You have some very nice photos and sketches there. :waytogo:

Excellent sketch of Lansberg and Reinhold! I love the way your sketch gets "real black" near the terminator. Very naturalistic.

Frank, I missed the Moon this last week (and weather is very cloudy for the week to come). So I will compensate that with looking at your fine sketch :jump:

Uwe, Norme and Jef,

Thank you guys.

I look forward to seeing sketches from all of you.
This cloudy time of year in the North we need to jump on sketching opportunities.

Frank :)
