The LRGB workflow I follow is uses either 3 or 4 filters

  • Red
  • Green
  • Blue
  • Luminance (optional)

LRGB images are much more difficult for those of us in heavily light polluted locations, but it is possible. The key to being successful with LRGB images is to wait for the target to be higher in the sky, to image during nights with high transparency, and to avoid the moon.

For luminance, this workflow will work with either a synthetic luminance or a real luminance. A real luminance is preferred if you are able to image through a light pollution suppressing filter as this will allow for longer exposures, which means more signal and detail. If this filter is not available, simply use a synthetic luminance.

Note: I use this as my personal guidebook for image processing. There are so many things to learn along the way and placing them in a blog will help me remember how and why I do certain things.
