This is a closer view of the Alpine Valley and the narrow rill down the centre of the valley
can just be seen. The valley is 150 Km long by 8 Km wide and is remarkably straight. Down the centre of the valley is a
narrow rill only 0.17 arc sec wide which corresponds to about 700 metres on the Moon. It is remarkable to be able to resolve
this with a 254 mm telescope. The picture was taken with a ToUcam attached to my LX200 with a X2 adaptor lens on 1st March 2004, a night of exceptional seeing, when the Moon was 9.7 days old. Small craters are named after a nearby large crater with A, B, etc, appended. In this case the two small craters labelled A and B are in fact Egede A and Egede B. |
