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. :)
