After reading the reviews on here and the web about Alignmaster I have decided to give the free trial a go just to see how close my polar alignment is.
I'm going to use my DSI and PHD on my EQ6 along with EQMod to perform the tests. But the problem is PHD, when using the bullseye overlay with the DSI, there is an overscan area at the bottom of the captured images thus making the bullseye not lining up centrally?
Please see attached. (This screen grab was captured during the day)
That is not an issue at all, As long as the crosshairs stay on the same spot all the time. The alignmaster software simply wants the stars to be placed on the same spot multiple times, the position of that place can be anywhere on the image.
