Another Ha Combine question

[vicent_peris]

Hello all,

well, almost all the work is done. Now I'm going to write the article describing the method. These are the results:

- The RGB image, with histogram adjustment, HDRWT (6 layers, 1 iteration and luminance mask option active), and a mild color saturation raising:




- The HaRGB image with a x12 gaing in H-alpha. The processing steps are the same than in the above image:





Jack, I've uploaded the combined FITS file to your directory for your work. Let me some days to write the article, ok?

After this article, I will investigate in applying this method to more narrowband filters... Hope this will work too!



Best regards,
Vicent.

Good result and I am looking forward to tutorial and any process tools that come from this.  I really like the color of the Ha Image.  I used that same technique wioth a re do of another image and extracting the Lab a and b and inserting the Lab a and b from the regular RGB is a cool trick!

Yes, it's a good trick.  :lol:  But it will contaminate the H-alpha signal with noise from the R image, so you must have really good R data to do this.

The article will have two parts. The first will have a bit of theory and will explain the basic principles of the algorithm, and the second will cover the practical application of the method. Tomorrow I have written the 50% of the first part.
