Crater Diophantus and Delisle

[Mike JW]

What brought me to this area was I noted the Lunar 200 list - L198 (Crater Louise and Rima Diophantus). I was unable to observe either, despite x 300+ mag and a 15" scope to enable fine detail to be picked up.

At the top is Diophantus (tiny Diophantus C just above it). This crater is about 11km diameter and seems to lack a central peak. Just below it in the lighter region is where crater Louise should be at the top of a raised area. Interestingly the lighter region appears to be part of a ray of lighter material. I tracked it back to Aristarchus.? Diophnatus B is the lonely 6km diameter crater off to the left. Delisle is about 15km diameter and had a noticeably rough southern slope (up in my sketch). It also lacked a central peak. The mountain range near by is Mons Delisle (badly sketched - never have cracked sketching mountains). The mountain shadows revealed 4 major peaks in descending order. At the southern end there were definite hints of rough terrain.

Thats an excellent sketch Mike. I find the Moon to be the hardest of all astronomical targets to sketch, so thanks for fanning the flame. I need to sharpen my pencils as the night's get milder and the Moon gets higher over the spring months.

Hello Mike,

I missed this sketch a week ago. That's excellent! I like especially the small bright stripes of the bright Diophantus rim in the sunlight!

Hi Achim,

Thanks for the feedback.

I use a white gel pen to do the stripes  but it got dulled down when I scanned the sketch, so I added them back in using Photoshop.
