Beautifully done at low sun. This is always tough to do, capturing craters with the Moon at low altitude as it races to the horizon. Langrenus crater looks great.

thanks for the feedback!
Regarding the paper I must admit that the scan is poor quality. The paper itself is nearly black - not grey.

An excellent observation of Langrenus. Complex detail within and surround the crater. Thank you for sharing it with us all.

I always boost the contrast (black/white) after scanning with Corel Paint Shop Pro (Photoshop or GIMP will work too). I tried it on your sketch to give you an idea.
The paper itself is nearly black - not grey.

yes, I should have played a bit more with all the settings...Thanks for doing that for me.
