Light polution removal in a RGB combined image
I am processing a RGB combined image using an extracted Ha and OIII channel to to simulate a HOO color image. My question is, would it be better to do the light pollution removal on each channel before I combine them into an image or combine the channels first then do light pollution removal?
That is a good question and unfortunately the answer is "it depends". If there is a big difference in light pollution between Ha and OIII then it may be better to reduce it on the individual panels. If it is more or less the same then you can do it on the combined result. But you will need to try and see what works best for you.
