Before I bought my RASA, I asked the Solar System Imaging forum on Cloudy Nights why I hadn't seen any lunar images taken with the RASA. Several people who responded said that it wasn't viable "Because the RASA is too fast." The implication was that it would saturate at minimum gain/exposure. Others said that there wouldn't be any improvement over my Orion ED80T CF with the same camera.
After capturing data on the Horsehead and Rosette last night, I decided to give it a go...As it turns out, it wasn't difficult to do it, even with the small pixels of the ASI183MC. I set gain to half unity (55) and found that 4.7ms exposed around 50%. You don't know if you don't try.
Certainly, a sample of one doesn't prove anything, but I am very happy with how these results compared with my old ones. I estimated the seeing at about 3/5 from watching during capture, and that's supported by the FWHM I was achieving on the Rosette Nebula which was about as bad as normal for my area.
