The California Nebula

[kirkster501]

HaRGB, Samyang 135mm with G2-8300 CCD and Astrodon RGBHa (3nm)

20 x 5 min Ha and RGB, 8 x 5 mins each

Developed in PixInsight and Photoshop.  Lots of blending of the Ha channel in various combinations with the primary colours (predominantly red but small amounts added to blue and green as well).  Recombined them then a master luminance of a blend of Red and Ha added to the resulting RGB.

Hope you like it

Very nice Steve, just working on my version with data from the last three years so it's a bit tedious to say the least 😂

Very nice 😀

The nebula is looking great.  The starfield has that business you get with widefield images.  Have you tried the Starnet PI script?

Yes Martin, that's what I used to extract the Ha from the star-field and then blend that in various combinations with the R channel at 60% and the Blue and Green at 20%.  I used pixelmath to put the RGB back together.  And then I used the Red_Ha combination again as a luminance to the reconstructed RGB blended at 50:50.
