NGC7000 area : Total rework in my processing methods

[Catanonia]

I have been trying for ages to get my processing of Ha and LRGB images right. Thanks to all especially Olly for the advice on how to blend it all.

I thought I was doing it right, but had a complete re think on the methods used and I think I have cracked it.

Here is the reworked image in HaRGB.

I took the RGB (45mins each channel in 5 min subs) and then used the Ha layered 'lighten' method to combine the data. The Ha was 100mins in 10 min subs.

Had a play and slowly merged in the Ha and looks ok i think.

Here is the full size image

Ah, that's getting really good. You are showing plenty of faint dusty detail between the nebulae.

Great detail showing through, looks a little pink though?

I think that's a cracker. I love the fine dust details and contrast. It 'feels' really deep if you know what I mean.

good depth of exposure there, you just need to figure out why most of the stars are reddish and the rest white. Good, natural star colour is difficult to achieve but well worth the effort.

Yup, that's a tough one. What were the RGB stars like? Is it the Ha that has cooked them, I wonder? You can select the stars (via Noel's Actions or Martin B's tutorial), expand and feather the selection, then partially erase them from th Ha layer boefore flattening it onto the red.

Yes, am loosing star colour with the merging of Ha. Not sure what is going on and need to perfect my technique a little more with it.

Will carry on playing with the work cycle and see if I can rectify it.

Love this forum and the expert help that is available, really helps you progress so a massive thanks to all
