First decent wx since last year so I used a moonlit night to check things out. I just installed ver .169 and I’m not sure if its the cause of my problem or something else has messed things up over the winter. I had always had decent V curves - a little bump at the first exposure but otherwise it would do a decent job of focusing. I start off using a Bahtinov mask and grabber to get in focus and the HFD numbers reported by SGPro are what I expect for my OTA, camera and environmental conditions (.8-1.2 or so, binned 2x2, QSI683). I was verifying AF and thought I’d try backlash comp, 50 seems about right and it indeed does eliminate the first bump in the curve. But the V curve is now mostly gone, AF fails.
Going back to my setup from last year, I eliminated backlash comp and it still doesn’t won’t give me a decent focus. I’m tempted to re-install vers .151 which was the previous version I had successfully used but before I do that, any thoughts on what’s happening? I don’t have the greatest focuser/controller on my Explore Scientific ED127-FCD100 (stock focuser, impossible to replace, Rigel controller) so they may be the problem but they worked quite well 4 months ago.
