I have in the past used the autofocus routines successfully with a 925mm scope and feathertouch focuser with the focuslynx motorised focuser.
I have a new RC 12 scope (2483mm fl) and a moonlite focuser and high res stepper motor. I have set the focus step size to 37 per the instructions in the SGP manual. I am struggling to get the focus routine to work. I am not getting v curves but rather fairly random patterns. Often the thing gets completely lost and ends up way away from focus. I have tried adjusting step size and Nebula rejection parameters without success. I can get reasonable focus using the hand controller on the focuser so I don’t think the focus hardware is to blame as such. Sometimes SGP gets a reasonable focus point but the curves are not convincing like I get regularly with my other scope (V curves). I am only trying to focus through the Lum filter for now.
I have read a few other comments about problems focusing longer focal lengths with SGP. What else should I be trying?
