Description

Just a quick test to see how I might re-expose the Cat's Eye Nebula. This is from an 8" in a 19.5 SQM sky.

The original processed results from August 2016 is here...

My main focus with the reprocessing was more detail, less noise, and arguably more natural colors using PCC. The PI HDR insertion with PixelMath is slightly visible. Something that would need more attention with low SNR data.

This is HaLRGB. I recall the nights were exceptionally stable. Detail benefited from 774 of my best 60-second luminance subs (12.9 hours).
