Any of the things you mentioned could contribute to that. a bad PEC could certainly create havoc too
best way is to upload your guidelogs and we can do some analysis
OK, I have uploaded the log from this session.
You should see a couple short guiding runs as I played around with it before starting an imaging run. Then there should be a long 100 minute guiding run while I imaged. During that 100 minute imaging run I did a PEC train, watched it for a bit, then turned PEC off and left it off. Some time later (still during that 100 minute run) I changed RA aggressiveness from 70 to 90, then to 100 and then back to 90 (as I recall).
Except for the RA aggressiveness, all other settings are per the last guiding assistant run. Note that DEC backlash started around 1000mS but drifted upwards from there to a little north of 2000mS as I recall. DEC guiding looked near perfect to me. RA looked pretty good as well aside from the occasional vaguely periodic swings +/- 2" or thereabouts.
I'll be interested to hear what you find.
