i have some nice Ha data of M42 I’m trying to layer on top of a much smaller field OSC image. I created the individual RGB channels masters and ran Alignment with the Ha master and loaded into the Color Combine. Because APP insisted on using the big Ha field as the reference I get a very large monochrome image with a smaller rectangle of the color integration part in the middle. I really want to just work on that smaller portion of the image in the color combine module. How can I do that?

Hi @whixson,

You can do this, by

  1. manually setting the reference in 4) and
  2. in 6) integrate, choosing the reference composition mode 😉

Kind regards,
