Gotta be some of the hardest data ive ever processed tbh, but extremely pleased with result! DSNR leaves some pixels at the highlights of M57, pretty sure its because how bright it was in linear, either way, signal far surpassed what i assumed was possible at F6 and under 3h of data (for the SNR part)

I used old data as a blended luminance as it was significantly sharper than my narrow data

Scope: Celestron C8 @ F6.3 and F10
Mount: HEQ 5 pro guided
Guiding: ZWO OAG v2
Guide cam: ASI 120MM mini
Imaging cams: ASI 294MC pro, Nikon D3500 full spectrum
Filters: Optolong Lenhance triband + non
Exposure narrowband: 30x300s (2h 30m ASI 294MC) F6.3
Exposure full spectrum: 30x300s (2h 30m Nikon) F10

ive had the same problem with dsnr, basically i create a luminance mask and under it, replace the post-dsnr image with the pre-dsnr image

#

nice image too

For sure, I tried that with a old process and it looks really weird having artificial RGB stars with the C8, so id have to shoot actual stars lol
