I've had some trouble with my guiding that I'd like to understand, I've never really looked too much at guiding logs and I'd like to know if it's possible to read out a possible cause. So my first log is from January showing good guiding and the next log is from April and the guiding is significantly worse. It seems to mostly be in RA and I've felt the RA axis does have some play but I'm not sure if that's all there is too it. Isn't the calibration supposed to manage backlash, but perhaps it's too much in my case?
