I received the Skywatcher 0.85x reducer / corrector and reshoot Eta Carinae with it. I'm very impressed with the edge of field improvement.
I also received my lightbox (thanks Exfso!) so I used flats as well. No darks as I tried some at ISO 1600 and saw little difference. I've also gone to ISO 800 for this. Does anyone think it needs darks?
