field of view needed for polar alignment
field of view needed for polar alignment
Would like to use main scope and camera for polar alignment function in sharpcap (do not have autoguiding). I read in an older post that I would need .5 degree field of view in either direction. Does this mean .5 degrees for the shorter dimension of the camera chip?

Hi,
Yes, 0.5° for the shorter direction is pretty much the minimum requirement – better if you can manage 1° for the shorter direction, but in most cases 0.5° will do.
Cheers, Robin

Thank you for that clarification. Very helpful.

It often works with only 0.4° too...It is almost always sufficient...for me
