@Anthonyexmouth I imaged the comet with a Celestron RASA 8 at f2 with an ASI294MC Pro cooled to -20°C. Processed in PI. Image is cropped to remove stacking edges

Ah cool, so imaging at 480mm isn't too short then. I'll give that comet a go if it clears. Not taken my 294 down to -20, do you think its worth pushing it a bit lower than my usual -15?

Probably not much difference but I use -20°C as a standard. Easily reached in winter and in range for summer nights.

last summer i found i was running at 85% to maintain -15 so stuck with that throughout the year. not sure i could get to -20 all year down here in devon.
