Description

M52 open cluster including Bubble Nebula.

Captured over the course of 5 nights near the new moon.

10 hours of luminance (600x60s)

1.5 hours each of R/G/B (100x60s for R, G, B)

8 hours of HA (100x300s)

Workflow:

Lum: Calibration, ABE, Histogram Transformation

R/G/B: Calibration, RGB Combine, ABE, Histogram Transformation, Background Calibration, Color Correction, LRGB Combine with Lum

HA: Calibration, ABE, Histogram Transformation, NBLRGB Combine Script

LHaRGB: Histogram Transform to clean up a bit

I didn't want to lose any nebulosity, so I didn't do much of a crop. Thus, my unmatched focal reducer is showing its oblong stars, but I find it easy to ignore.
