I'd like to learn how to process stars separately, particularly adding RGB stars to a narrowband image. I'd also like to learn how to layer an Ha image onto an RGB image. Does APP have an algorithm to help with these tasks? Thanks!

@jehoener It is currently not possible to process stars separately but this functionality will be added to the upcoming version 1.083. See
As for adding Ha to an RGB image, you will need to split the RGB channels into separate R, G and B images and then use Combine RGB in tab 9 to blend them together.
