Guiding issue
I tried guiding with PhD2 over the weekend and went through the calibration process once I got everything aligned etc. Calibration seemed to go smoothing without PhD having a fit about anything and I started guiding. The graph immediately took a nose dive and never recovered beyond issuing corrections which simply moved the mount between 4 and 6 pixels in whatever direction PhD fancied at that point in time. I disconnected the guiding and moved to unguided shots just to get something out of a night out.
The mount was polar aligned well and I was able to keep an object on the CCD chip for an hour before needing to nudge it back towards the centre so I am pretty sure there was nothing mechanical at play this time. I didn't have a spare ST4 cable with me and now it is cloudy and raining again. Is my assumption that the cable is likely the cause of the issue correct?
Thanks
Brian
