Description

Very narrow window to capture this object from 42 degrees N. Kept 100 of 160 subs due to aggressive light domes. Will push the color on a future revision.

Revision E - update: Kept the best 60 frames for the final color push (setting quarter moon). 60% culling rate.

Description: Reprocess of this summers DSLR data. Noticed that the 60Da was applying aggressive internal amp glow control resulting in the DARK average ADU slightly lower than BIAS ADU, as a result normal calibration was clipping the last couple electrons from noise floor. Restacked using Light-Dark and Flat-Darkflat(using bias) the lower tones came out quite a bit better.
