Hi can anyone advise the focus step number that works well with an Esatto 3"
Had the Senso Senso before and 180 steps worked well with my Tak 85EDX focuser
I read because of the sensitivity of Esatto and the large number of points (steps) a much higher number a steps is required I have read between 3500 to 6000?
If anyone has practical experience of how many steps is suitable for a refractor scope to get a good curve based on 8 points
Thanks
