A very quick and dirty Prawn.
I only managed to salvage 7 x 5 minutes out of a 2 hour session. I lost the rest due to focuser troubles. Ends up that the 20D + Field Flattener is just too much for it to handle it slipped quite early in the session without my realising it.
I didn't bother taking flats after that.
Anyway, I just thought I'd post proof that I was taking advantage of the clear skies we'd been lucky to have this weekend.
