Is there a software package that will center then keep a star in the exact center of the field of view while collimating? I find it very frustrating to make small movements while dialing in collimation only to have to recenter the star every time.
I'd like to use it on defocused stars, and with a tri-Bahtinov mask.
Does anything like that exist?
As I think about it, PHD is about as close as I'm aware, but I'm afraid it would loose the star as I monkeyed around with focus or used a mask.
