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.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
