Observing Notes:

This was my first experimental use of a new astro-camera, new astro-imaging software and new image stacking software so I didn’t really know what I was doing most of the time…………

However, this test shot came out reasonably well, although I might have given more attention to focusing. The more you zoom in on the Moon, the more difficult focusing becomes, due to atmospheric conditions.

The image was taken less than 48 hours after a lunar eclipse, which was completely clouded out here.
