Quote from: Mac on Jul 03, 2022, 22:55:37If you dont use a Hb filter then you never have any blue in your images, Oiii is green, Ha red, If you use another filter and then use that as a blue then you end up with false colour images.You used to be able to get a light pollution filter which combined all three of those in to one band pass filter and that was prety good. Mine is somewhere, probably in a box in the garage......The problem now days is everyone has jumpped on to the LED lighting and the problem with thats is the pollution is across the entire spectrum, so no amount of narrow band will really help.Mac.
