Revelling in the cold

Standard

The revelling won’t last, though I daresay the cold will.  So I nipped out with the 10″ to take a quick look at the Moon, as everything else was wiped out by it.

I always like the waxing gibbous phase, which conveniently brings some of my favourite features to the terminator.  I took a lot of snaps through the eyepiece; always frustrating to find that while one segment is pretty good, other areas come out blurred.  And the Moon image in the eyepiece was surprisingly zizzy considering it isn’t warm, which won’t have helped to get a sharp image.  I’ve turned the pictures upside down to make them right way up, and now they look peculiar to me.

1-waxing-gibbous-10-nov-2016There’s something very satisfying about Clavius, with its arc of smaller craters diminishing gradually in size like Russian dolls.  The camera managed to pick up the central peak in Rutherfurd (on the southern rim) and the smaller craters D C N and J (running away from Rutherfurd in an arc).  The unevenness of the crater walls is obvious, and I see there is a tiny hint of the rather mashed down central peaks (inboard of C, as it were) and hints of some of the other minor craters in the interior.  I haven’t attempted to identify all the surrounding craters – this part of the surface is a bit busy.

It would be too much to expect to image any of the rimae with my feeble equipment.
