Hi Nicholas I'm a little confused/concerned about these large and fairly instant jumps in DEC I see it happened a couple of times. I don't see it affecting RA, so it looks to me like something is loos

it's possible though this run reported no prior calibration issues - the calibration data prior to this wasn't in this guidelog. It looks like maybe the guidescope slipped and/or was rotated when the

I found an earlier run that looks better - and by "better" i mean relatively better than previous. At least this one kind of makes some sense: The previous run was unguided data There were significant

Hi Andrew In general it looks good, but I think the main limiter for you is your min move is set too high. You are achieving about 0.5" RMS with DEC and RA nearly identical, and it turns out your min
