tried again for NGC 1023 (Halifax)

Asked BGO to reshoot galaxy NGC 1023. A Finest target originally imaged in August 2016, the colour channel data was badly streaked. 

Resubmitted the job a few days back.

It came back with bad data again. Tracking problems in the red; green and blue sync errors. Not to mention donuts.

Was it the poor conditions? The CSC showed cloud: 70% covered; ECMWF: cloud 65%; transparency: too cloudy to forecast; seeing: bad 1/5; with the Moon altitude at 21.9. Hrrm.
