LRGB+Ha

Post by Heno »

Hi
I'm sure there is a simple way to do this, but I cannot figure it out.
With data from LRGB and Ha, how do I load these five data sets into the compose module? :think:

Not sure if 'simple' and astrophotography fit in the same sentence :-) but what you need to do is create a new red channel by combining Ha and red and then loading the new combined channel.

Ivo gave a description here:

You can also use the Ha as a luminance channel or combine it with luminance data.

When I said simple, I was probably thinking about what Ivo says in the last sentence:
"This is one of those answers that are a lot less straightforward, as there are so many ways to achieve different goals. That said, I've been thinking of adding dedicated functionality to make adding visual Ha easier."
That functionality is what I was looking for. :D
Thanks for the information/thread link anyway. I will have to read that several times to grasp everything.
