Hi, I have been running my EQ8 mount successfully, over the years, using the Ekos Guide module set up to use a separate guider camera. Just recently I have noticed that the drift plot is showing the guidance is off centre:



This is now causing my images to veer out of my 2 arcsec limit. I am guessing that the instructions sent to the EQ8 (set point) and the actual returned measured position do not agree, particularly in dRA axis. I have checked and adjusted polar alignment which seems okay. Is this an issue with the EQ8 hardware or is there something else I can do to locate/fix the actual problem?

Many thanks,
Dave
