Not sure if this will help, BUT, I have the sbig 8300 with the sbig OAG, I cannot really rotate the camera much at all because it will end up hitting something . What I did was plate solve an image and determine that my camera was always oriented 28 degrees , then I opened the Mosaic Wizard and whatever my target was I rotate to 28 degrees using the little slider within the Wizard window. Now I have my starting point. The Wizard will figure out how many panels I need to capture my 28 degree image whether it is a Mosaic or not. I can always rotate the final result in pixinsight. Sure was a cheap way out AND I don't have to run out in the dark and turn the camera around in circles. Man, is it accurate !!
Clear Skies,
