Description

M101 - Pinwheel Galaxy
Taken over 2 nights to trial a new guide camera (QHY5L-II mono). The guiding was much better than with my old camera. However I'm still experiencing camera timeouts. I think I have resolved this by running the camera on a dedicated USB cable rather than through a hub, but time will tell. I'm fairly pleased with the result given the ligher skies that we have at this time of year with it never really getting truly dark.
