Description

Magnitude 13

Size 147" x 114"

Teal added to B G Channel of RGB using PixelMath then HA added to R Channel in Photoshop after star reduction.

Minimal NB images used thanks to Topaz denoise. 3D LUT Saturation Contrast LUT used to separate R and Teal... the HA overlaps the O-III in the center and makes a mess otherwise.
