Description

Another attempt at processing the Omega nebula in Sagittarius with AstroPixel Processor, and a closer crop. I think I like this version better despite the somewhat convoluted processing route.

Ha (100% Red, 25% Blue, 25% Lum) x 1.000 intensity.

O (100% Green, 100% Blue) x 8.000 intensity.

S (100% Green) x 10.00 intensity.

SW 8 inch/f5 Newtonian, ASI1600mm Pro, Gain 250, Temp -20C, 180 x 30sec exposures for each channel, unguided.

Data processing - APP/LR/TDN-AI.
