I messed up! See this video for the fix. ruclips.net/video/Q0uZVE0jniY/видео.html I made a mistake in the processing of this image. On a Dutch forum somebody mentioned that the resulting image seems to have way less detail in the Ha than one might expect from seeing the Ha stack.
I'm enjoying this series. Glad to see someone using some of the free tools that I am learning, myself. I'll keep watching as long as you keep posting. :)
thank you! I have a question if you don't mind: often when using a composite green channel - some nebula parts which should be blue (strong signal in oxygen) appears to be white. is it how it is supposed to be? or is there any trick to avoid that and get a nice blue color in oxygen areas, instead of white ?
In the processing there is a step where you color balance the data. You generally do this before stretching. During the stretching phase, you then have a better chance retaining the blue color. Siril has some nice tools for that (free). This page has some explanations to that regard: siril.org/tutorials/rgb_composition/#2-equalizing-image-levels
