No Mine are the same issue. So far I've noticed them right after the dither process. I'm thinking the issue occurs if the star fades a bit due to cloud. I basically want to figure out which images would have been unguided so I can double check the image before trying to preprocess it.

Here are similar snips from my logs

07:05:05 (guider error n/a or too high, try #49)
07:05:07 (ex=0.50 ey=1.16)
07:05:07 (guider error n/a or too high, try #50)
07:05:07 (stopping the autoguider)
07:05:07 **Imaging error: **Excessive guiding errors just before image acquisition
07:05:07 Will try image again, this time unguided.
07:05:07 (taking 600 sec. exposure, Lum filter, binning = 1)

(guider error n/a or too high, try #47)
08:09:31 (ex=0.25 ey=0.66)
08:09:31 (guided dither, 1 good cycles)
08:09:34 (ex=0.61 ey=0.76)
08:09:34 (guided dither, 2 good cycles)
08:09:36 (ex=0.18 ey=0.61)
