Description: Comet-Tracked without rejection. The total exposure start to finish was 2h 47m wherein the Comet moved 0.32 degrees. Unfortunately I forgot to set the exposure plan to loop during the first hour (sleeping next to the telescope, my intention was to get up every hour to run the refocusing routine) so there is a large gap after the first set of exposures
