Crescent Nebula (NGC6888) HaRGB

Here's my rendition of the Crescent Nebula NGC6888 in HaRGB. 

1.5hr each of R,G&B (90 x 60s subs) and about 5 hours of Ha, captured using ZWO ASI1600mm pro with SW ED80 DS Pro. Inages captured with APT, stacked in Siril with darks, flats and flat darks, processed in PS.

Each channel stretched separately, then combined in PS to make RGB image, followed by Siril's photometric colour calibration. Starless Ha added to Red channel with blend mode lighten.

HaR also added as a luminosity layer, followed by some final stretches and selective colour and vibrance/saturation tweaks.

Hope you like. Any feedback/constructive criticism is welcome!

Your blue stars are slightly green (or it may just be my phone) other than that you've got a very nice image there 

Thanks!

Just looking at the stars again, hard to decide if they are on the green side or not, I ran HVLG (high setting) but I guess it could have missed a bit

Must be my phone then. HVLG always does a good job for me
