attached is an image of the laptop monitoring the ra /dec error with phd2. while asiair was imaging and was connected to the mount.
Just to be clear I think this is pretty good (polar alignment was crap, we are really just seeing pec and probably some atmospheric noise certainly no gremlin spikes)
On the subject of my bad polar alighment, I align repeatedly with asiAir get it under 30 arc seconds, but meansuring it its often 8 arc minutes out!
My suspicion is that when asiair requests the mount to turn 20 degrees in RA, it might only do 19.6 because of these issues I have, resulting in the maths being ot and the polar alignment ultimatly being wrong. I look forward to trying the polar alignement without the 120mm to see if its aligns better
