Getting correct colours with Ha(L)RGB
Posted: Wed Sep 25, 2019 9:48 pm
I was fortunate enough to find some great data from a post in Cloudy Nights of M16. The imager took HA, R G and B. So as there's no luminance data, I used Ha as L in the compose module. The red colour is really off I feel.
What would be some techniques to make the ha data as naturally red as possible? Here are a few images.
This is the default scientific colour:
This is scientific colour as well but with the stars sampled to get a proper white balance:
Finally this is the stars sampled version with green reduced ( a lot):
As you can see the red is not right. I also created a synthetic L via RGB, then blended it 50/50 with the HA to create an L for LRGB. It still looks similar though. Any comments are appreciated!
