Copernicus crater 96km, Day 9 Moon

Iconic terraced crater with slump blocks and 2 central peaks. There is a prominent ray system of ejecta.

 

I went with lower gain on the camera than I usually use since this is a bright target with good SNR. Because of this I could be choosier about selecting just the best frames from the 5000 frame video - just 10%.

 

10% of 5000 frames

 

Day 9 waxing Moon. Good seeing.
