Description

This version looks like the famous photo captured by Hubble Space Telescope.

Helix nebula (HST) version:

https://www.spacetelescope.org/images/opo0432b/

Ha: 13*10min

O: 12*10min

First, I LinearFit O with Ha, and set three parameters for HOO combination.

Red = (1 - i) * Ha + i * O

Green = j * Ha + (1-j) * O

Blue = k * Ha + (1-k) * O

Then run an algorithm to get a lot of photos generated by different combination parameters ( i ,j ,k). Then I found my favorite one.

Finally, create masks to control color of different part using PixMath.
