Description

Half of this came from the Almost Heaven Star Party and the other half came from home but from an SNR perspective the AHSP data probably dominates the weighting.

Processing notes:

ABE on R, B and G masters

Channel Combination

Dynamic Crop

PCC

MLT chrominance & luminance noise reduction

Masked Stretch

LHE

MLT sharpening

Adam Block's star de-emphasis

Curves for contrast

Dark Structure Enhance

With this framing it reminds me more of E.T.'s finger reaching into the frame than an elephant trunk but that's probably just me.
