Re: Tracking problem with Mach 1
I was having a problem with tracking last night.....the mount slewed to coordinates in SGP and APCC, but shortThere doesn't appear to be any logs that cover the time at which your image was made according to the images FITS header which interestingly says was taken at 4:42 am, which is one minute *after* you posted (which could means an inaccurate computer time).
I did a scan of your logs and there are a few instances of Solar rate being used, which could cause trailing like that.
Other than that it could be something like poor polar alignment, loose/slipping clutch, or a tugging cable.
