Thanks Marc,
I know theres a real red cast. I've never had as much before.
Normally my images look a bit red coming out of DSS and after stretching and sharpening ive never needed to colour balance but I've been doing orion etc which have a fair bit of red anyway.
My flats have a real red tinge to them, maybe thats the problem.
I'm not sure if i have to W/B before I image or not.
Someone here might be able to help.
Also i sympathize with people who image in the cities.
It must be like a full moon all the time!!!.
Im pretty lucky here to have to have virtually no light pollution.
Heres one of my flats plus histogram.
Not sure if i need to colour balance everything before i stack or after?
Cheers
Andy
