Sebastion:

Perhaps a couple of suggestions you can try:

Have you done anything with periodic error correction? If you don't have PEMPro you can download it and use it free for like a month. More than enough time to analyze your PE and send a correction curve to the mount.

Try increasing your correction pulses from 2500 to 3200. Multiple pulses show not enough movement is occurring.

Try increasing your RA aggression to 75 or 80 and your Hysteresis to 20. Increasing the latter often smooths the corrections into shorter but larger pulses, learning from past behavior.

Cut exposures from 4 to 1 to 2 seconds so corrections are made more often. Also try turning off the dithering until you try a few adjustments.?

Click on the brain to make sure you are using the right focal length, etc. Sometimes I have forgotten this when changing rigs. Also a new darks library is needed if you changed guiding cams.

Hope some of the above help. Perhaps you have already tried a few or all of these.

Good luck!

John
