Transparency started out so poor that you barely see Mars with the naked eye. If figured if the conditions persisted, monochrome imaging would be very difficult. So I decided to try the one shot color cam. I had to go with a 40ms exposure with the gain nearly maxed out. With those settings the frame rate will no more than 25fps.
The sky decided to clear out a bit later so I was able to do a monochrome RGB sequence. R and G were captured at 200fps while the B was at 100fps. Seeing was good all along. Focus was always easy to achieve. This was not really a fair comparison of the two cameras, but it still amazes me how well the OSC performed in such poor transparency.
The RGB image came out much sharper. There does appear to be some dust activity south of Cimmerium. Other than the polar cap, the dust cloud was the brightest feature in the G channel. Also, Arsia and Olympus appear as dark spots near the terminator. Someone correct me if I'm wrong, but believe that indicates considerable atmospheric dust. It enhances the contrast of the mountains.
