Elephant's Trunk Nebula (IC 1396) - SHO

First proper run at the Elephant's Trunk in SHO, but I think there's some issue with flats so some gradient issues. Still, it seems to work in this square crop, and is good progress from earlier attempts. Will run another stack to see if I can further improve. Not sure yet about the color balance either. Probably a work in progress... :-)

Description: Re-stacked with refined flats and some ABE. Crisper too, but different color balance. Not sure if better, just different.

Description: Re-stacked in APP, re-combined in PI, and re-processed from scratch in LR. Fixed the vignette at bottom right that was forcing the square crop too. *Now* I'm happy. :-)

Description: The purple and slightly hazy appearance bothered me, so after reconsidering for a week, I boosted contrast in various ways for aesthetics, while trying to not going too crazy with the saturation.

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.
