Description

This is a reprocess of my prior image from September 2019.

Skies were relatively dark (21.4) and steady (1.8") during luminance capture. But with only 2 hours of luminance, denoise was a challenge.

I feel this version may be a bit more natural with less noise and minimized red halos around stars from red acquisition during an unsteady period.

I also cropped closer to hide the noisier dark nebulosity and rotated 180 to match some APOD reference shots. (-:
