Hi Ron,Thanks for the interest. Unfortuanately I did not take any screen shots and the weather has closed in again. I have attached the guiding logs. Everything was fine until the meridian flip which on the logs is line 2145. The guider did a recalibration but at the next dither it takes much longer to complete the dither. The oscillation were in RA mainly. During this period I was making on the fly changes to RA aggression and predictive components. The next few dither had a similar prolonged adjustment period then the settling to normal post dither behaviour coincided with the change to one pulse dither. After which I ran out of time. I dont remember any issues with loss of SNR etc but the guiding log is the only log I have. I will need a bit more time to explore if this behaviour repeats.
Cheers
Mike
