Is there anyway or an easy to way to combine a red, green and blue image to give me a colour image ?

I have a image of the moon I took using a red, green and blue filter but need to combine them.

Have you tried:

  1. Create a new blank document (of the same size as your images) with a single layer,
  2. Open the Channels panel and paste your red image into the Background Red channel.
  3. Do the same with the green and blue images.

If that fails try copy-paste of the red channel of your red image to the red channel of your new blank file. Then the same for the other two.

I have an (untested) idea from somewhere that the Add blend mode on your three layers may give you what you are after.
