So, I have a persistent problem when trying to use auto-guiding. The telescope likes to oscillate back and forth in DEC and sometimes in RA. I originally assumed my mount just wasn't very good but after upgrading to a celestron CGEM, the problem is still there, although not as bad. The guider is an off-axis guider so I don't think it is a flexure issue. I use TheSkyX for guiding and imaging. I'm imaging at a somewhat long focal length of 1.4m, but I would still expect the auto-guiding to not smear the stars around. I also try to make sure my alignment is good before imaging by performing a drift alignment procedure. I have tried to use the antibacklash controls on my mount and TheSkyX but it doesn't seem to help much. Has anyone else dealt with such problems and have any advice for improvements I can make?
