116 x 300 sec lights (9h 40m)
Preprocessing DSS post processing with PixInsight and Adobe Lightroom Mobile.
I extracted a lum layer and ran it through Ez Decon and Ez Denoise. Color layer was run through EZ denoise and then several passes through arcsinh stretch. The lum layer was passed through EZ soft stretch. The two were then recombined using LRGB recombinantation with color denoise. A few light passes through curves to enhance contrast between red and blue nebula while leaving the brown in tact. SCNR a couple times to remove any extra green. Then I moved it to Adobe lightroom mobile to optimize color for cell phone.
