Nice crack martin
I recently got the 40d that im using modified and utilizing a Astronomik UV/IR screw in. Once these clouds nick off we should go for a bit of a wonder to take some good deep sky time!
the 40d modified is unreal in Ha, the difference is huge! 5 min with a LPF and the UVIR on a equinox 80 ed Lagoon was bright red pre processing and the details where nice (from morley perth).
the original image of Eta that i had taken at 4 min shots flats darks subtracted was almost bright blue with a few hints of red around. Tonight im going to have a crack at it again! ill let you know how it goes.!
