Observing Report 22nd April 2010 (More Moon bits)

Posted by on April 25th 2010 in Astrostuff, Observing Reports, Pics

The skies on Thursday evening weren't the clearest I'd ever seen, there being a light haze obscuring the stars. The Moon, however, was reasonably clear, and with the seeing being fairly good I decided to do a bit of crater-spotting. In order to get a good look before the target went out of the field of view of the scope, I had to start before the sun went down, but that didn't seem to be an issue.

During the unusually short session I managed to see and image quite a few features, following is a small selection of what was on offer (mouseover for the occasional annotated versions).

Rupes Recta (Straight Wall) (67 miles long)
FOV approx 256 x 196 miles

 Rima Hyginus (133 miles long)
FOV approx 275 x 185 miles

Timocharis (21 miles dia.)
FOV approx 113 x 82 miles

Eratosthenes (35 miles dia.)
FOV approx 90 x 76 miles

 

Hadley Rille and Apollo 15 landing site
FOV approx 181 x 156 miles

Apollo 16 landing site
FOV approx 146 x 133 miles

Just in case you don't know your way around up there, here's some help:
