Ad Astra Observatory

After shooting the few large craters that I can identify, I started looking for other interesting craters, assuming I could look them up and ID them online.

This is Grimaldi, which was right on the lunar terminator tonight. It would have fit better with a 90deg rotation of the camera, but I wanted to maintain my orientation so that I didn’t get confused during processing.

North is more or less down in all these photos. shrug

(added 5/26/2011 — I checked the size of those small lumpy features seen on the floor of the crater, and I roughly estimate the largest one to be about 4 miles across, based on the resolution of the image and Grimaldi’s diameter)
