Tried getting some shots of Eta instead (well away from moon) sinking into the west.
Did some Eta shots a while ago as the Moon was beginning to encroach - shots became increasing bleached of any detail so I've given the moon a wide berth for my Ha imaging ever since. 7nm might give you a narrower window so to speak, but I would suggest avoiding the moon!

Spot on Doug. That's the other problem of course - guiding. Even at 11 degrees sep as Carl suggests, the QHY5 is going to be, I'd assume, totally saturated. Could be wrong though.
If only the Eta Carinae region wasn't so far over in the west by the time it gets dark.... oh well - it'll be cloudy tonight here in Sydney anyway.
Time to get that ArgoNavis me thinks. At least then I don't have to rely on star hopping based on...uhmm... invisible stars.
