This is my Rosette Nebula from last weekend. It's a mix of RGB and HOO from the OPTOLONG L-eNhance filter. I wanted to keep the colors natural, so I removed the stars from the Ha and O3 data and mixed it carefully to the RGB in Photoshop. I'm very happy with the result.

Very nice result Robert. Any chance you could tell us a bit about how you went about removing the stars and the blending in PS? I also have the Optolong filter and have been trying RGB combine in APP and also using layers in Photoshop. Not too pleased with the results!

That's a stunning image Robert.
Might very well be the new Starnet++ plugin? I have no PS knowledge, but that one seems very powerful. Beautiful image and blend!
Thanks Dave!
It's much easier to show than to discribe, but I will try. The Dual-filter data I split into it's three mono channels. For removing the stars I use starnet++. Then I process each channel seperatly (denoising, etc.). For the mixing in Photoshop I set the layers to blendmode screen. Then I add a "hui/saturation adjustment layer" for each mono-layer with a clipmask, set it to colorize, choose the color (0 for red, 120 for green and 240 for blue), saturation to 100, lightness to -50 as a starting point. Than I tweek the mono-layer transparency and "lightness in the hui/saturation layer" till I get the color I like. Usualy I have to add some curve and level adjustment layers too. I hope it's not too confusing.
CS, Robert
Many thanks for the workflow Robert. I'll have a read and try and get my head around that 😉
Regards Dave
