Sky are clear since somedays, so I can do images every night. But I have an issue with the guiding. After the MF is does'nt restart. This night, I was imaging M101 from 00:47 (45 images of 4 minutes). After the image 35, the guiding didn't run, just after the MF.
Hereunder the setting of calibration and the log file. Thank you for your help.
