Hello. I used Orion image stack with STC duo narrowband filter to try separate Ha and OIII channels and recombine them. Fuji X-T3, fujinon 55-200 at 200mm, STC duo Narrowband filter, 60x60 seconds,  iso 800, Flat, Dark and bias frames. I am quite pleased with the result considering the type of mount I use. APP is an amazing tool.
