I’ve used autofocus in SGP with perfecton for the past couple years with my refractors. I’ve recently setup a 11" RASA that has a FT focuser and I had a motor install for remote focusing.
A course setting before was 500 and fine was 80. With this thing I have course set at 3000 and fine at 1000. It still has major problems.
Any suggestions for settings. Because it’s a F2.2 scope it’s focus is very critical… but SGP seems to only use one (course) step size when doing a auto focus. It often gets me in the park, but no home runs - rather foul stars when zoomed. Any tips/tricks? It would be nice if SGP would switch down to a fine focus step as HFR numbers start to get under 3.5-4. (Kstars did this fine, it actually dials down the steps on its own to nail focus).
