Imaged the first half of last December, tossed about 20% of the subs but what was left was fairly decent data. 13.7 hours - not crazy deep, but enough that I only needed a small amount of noise reduction, MLT in the linear state and GREYCStoration final touch-up while non-linear.
Did most processing in PI, and finished with star halo reduction and local contrast enhancement (Bodoni toos) in PS.
See other revisions for a different color blend.
