I took a break this morning between targets to grab a quick set of images of the waning gibbous moon. The sky didn’t look hazy, but it didn’t look perfectly clear either, giving the sky a wonderful soft color. It was interesting to note that I was previously able to just barely capture the entire moon within a single field with my 10” f/6.3 LX200, but not this time. To capture the entire disk I had to take two sets of images and merge them into a single mosaic.

It is very interesting to see features on the moon illuminated by a setting sun instead of a rising sun as we normally do when it is in the evening sky. For example, in this image the Altai Scarp shows clearly as an outer ring of the Mare Nectaris impact basin. It is also neat to see the illuminated face of the Apennine mountain range and the far western shore of Oceanus Procellarum.

Neat stuff.
