Hi, I have posted this in plate solving as I think probably the solution lies there.
I use SGP and Framing & Mosaic wizard. In September I want to capture some images of M31 and to get it to fit the Canon DSLR frame, I need the image to sit across the diagonal of the frame. Common requirement I’m guessing.
Is there a way I can work out from a plate solve (i use local astrometry and elbrus) how much to rotate my camera - I just have the camera attached to the scope - no electronic rotator.
The only other way I can think to do it is to take an image of m31, roughly judge the angle I need to turn it and do that, bit tedious though and would require a number of iterations I’m guessing…
I have read the help file on rotators and didn’t find an answer there.
thanks for any pointers
