Very Nice Hugh! Stars look ok. Your on a roll well done!
I shot just under 5 hrs on the Helix during September/October new moons but it was just too hot for long exposures with DSLR, particularly the Sept subs, they were up around +29c. Pity, as I had very nice guiding, best I've achieved in fact. Oh well, think I'll stick to Hyperstar imaging during summer to keep the subs short.
Can't wait to see your NGC300.
Cheers
