Auto focus with my single speed Skywatcher focuser (on my ED80) it seems is just not going to happen: either the focuser shaft is too loose and focuser tube slips or it’s too tight for the focuser shaft to get enough grip to move it. The ZWO ASI1600MM-Pro, 8 position EFW and FF/FR are combined just too heavy (testing this with the scope pointed almost straight up). I guess I could try improving the mechanism and sand back the flat bit so there is greater contact between tube and shaft but get the feeling I might be fighting fate. Is this anyone else’s experience?
Got another 50 minutes manually focusing so happy. Stretched it all way further. Too much? Not sure with processing Ha so two versions here just stretched in iPhoto. Tried another in StarTools but it was a bit too extreme.
