Crater Piccolomini is the larger (90 km.) target to the north (inverted view – Newtonian scope). The floor was 60% in shadow and the central mountain peak was casting a shadow to the inner rim, a beautiful sight. It is at Piccolomini that we begin to see Rupes Altai radiating into the terminator shadow. Overlapping craters at the north rampart of Piccolomini added to the view. To the southwest in the sketch, crater Stiborius (45 km.) was in deep shadow with only the rim illuminated. I could have used that extra 30 minutes but I must say the enjoyment of the view left me pleased.
For this sketch I used: black Strathmore 400 Artagain paper, white and black Conte’
pastel pencils and a blending stump.
