Description

Great narrowband subject, Ha is very strong (also R), SII good and OIII poor.

Ha was very good even if my subs weren't optimal, roughly only half of them had high SNR, the others were either out of focus or bad due to thin clouds.

OIII didn't turn out strong no matter how many subs, SII was good even if not as good as Ha.

I tried also RGB to give stars proper colors but I didn't manage to combine it well with narrowband, need to improve my technique there.

Used the SHO Hubble palette and I had to use SCNR on the combined result to get rid of the green hue (probably expected given how strong Ha was).

Nevertheless I believe this is my best narrowband work so far, enjoy!
