Description

First light on my ASI294MC Pro with my RedCat 51, L-Extreme, and Star Adventurer 2i Pro. I'm in a Bortle 7 with intermittent clouds I had to pause and resume my sequence around, 99% waxing gibbous moon on the night.. ended up with about 60 minutes on it, 20 darks, bias and flats.

Captured on a Raspberry 4 with Astroberry / KStars / EKOS (first time using the PI, loved it!), stacked in DSS, and PixInsight process looked about like this:

Color Calibration
SCNR
EZ Denoise
Channel Extraction
EZ Soft Stretch
RGB Channel combo
Starnet++
Extract Starless,
Dump blue channel
Curves on green for luminosity
Pixel math: 0.6*Ha + 0.4Oii as new green
LRGB Combination: L=Ha, R=Ha, G=new green, B=oiii
Curves
SCNR
Dark Structure Enhance on starless layer,
Photoshop minimum on star mask
Recombine starless and star mask with Pixel Math

First time trying the 'Hubble palette' though I'm surely far off. i am looking for critique on my colors as i am slightly color deficient in one eye so certain colors are hard for me to really match so please be brutally honest on the image, I know my downfalls with colors and am working on ways to be able to use the data to find the perfect colors without relying on my eyes and on numbers instead.


Either way I am very very happy with how it has come out and it's definitely my best work to date.

Cheers and clear skies!
