This drawing done on Saturday 25th August shows a chain of three prominent craters: Ptolomaeus, Arzachel and Alphonsus. Arzachel is the topmost and (with a diameter of 100 km) smallest of the craters in the above image, Alphonsus is the middle one having a diameter of 121 km. With 158 km, the crater Ptolomaeus is the biggest of the craters visible in this drawing.
Soft pastel and charcoal on black paper.

Thanks Alex for you patience and guidance.
