I have downloaded some data which only contains OIII and Ha would I combine them using LRGB Combination or Channel combination? Using Ha in the L and R channels and OIII in the G and B channels?
There are a number of ways of doing it- but typically you will use channel combination, pixel math, or a whole host of scripts that mix this for you. For example you can use the NBColourMapper script that Mike Cranfield and I worked on which will allow you to color each channel however you would like.
