Deslandres is a very ancient crater from the pre-Nectarian era of bombardment (3.92-4.6 billion years ago). At low sun angles, and given its favorable location for observation, a whole host of features become visible on its floor. Several catenae can be seen as well as the outlines of buried craters. An interesting feature I saw at this low sun angle was a rille like feature ( graben like ) that ran from the southeast to the northwest crossing the northern portion of crater Lexell. This remained visible during the time I took to do this sketch. The floor also shows a slightly convex shape perhaps due to volcanic uplift (?). To the northwest, Rupes Recta was getting ready to make its debut with the rising sun, but alas by that time the moon was behind a line of trees. This sketch was done using my Ioptron 150 with a 9mm Televue Nagler. It was done with white Conte pencils, crayon and white charcoal. Started around 01:30 UT, finished at 0:240 UT July 21st. Thanks for looking...this is a really fine feature with this sun angle.
