Autumn Moon

Last night the skies suddenly cleared just before moonrise, so I thought I'd try to photograph an amazing feature called The Straight Wall. This lies to the east of a small crater, Birt, near the well-known triplet of Ptolemaeus, Alphonsus and Arzachel. The 120km long slip fault is only visible when the terminator runs close by: last night it wasn't! The close up shot was taken some months ago with a combination of 400mm lens and various converters: hopefully my new Maksutov will produce similar - or better - results when it arrives in two or three weeks.
