I'd like to combine images taken with the Optolong L-Extreme filter with images taken with the Optolong L-Pro filter. The goal is to capture the Ha and Oiii data, which restricts the star colors, and combine it with L-Pro data that DOES capture the star colors. I'd like to know if these get stacked together (I use Deep Sky Stacker) or do they get stacked separately, then combined in some way. I only use PhotoShop for post processing. Please let me know how you do this, or if there are any youtube videos our other websites that relate how to best do this.
