Tonight was a clear night, allowing me to test the plate solving in further detail.
Solving the coordinates from an existing image worked, also this night. I could load the retrieved coordinates into the target sequence. From the target sequence I chose “slew target” and then “center target”. Unfortunately, the latter step failed wit PlateSolve reporting an ‘Run-time eror ‘6’ Overflow’. See screenshot. Apparently, there is still something wrong with my setup. Any tips?
