I just got my ST-i camera for autoguiding but I have the color so that I could kill two birds with one stone. I have been wanting to upgrade from a Neximage burst and this was what I decided to do. However after two hours of trying to get a single good image or at least something I could work with I gave up and went back to the Neximage. The only difference I could tell is that I can control the gain. The ST-i is a lot more sensitive and I tried everything I could think of. Any help would be great. Thanks
Are you guiding with the ST-i? It's not meant to be a video stacking camera. See page 31 in this PDF. https://www.sbig.com/site/assets/files/2358/st-i_manual_1_0.pdf
