Revision title: SHO final

Early results of IC 410, poor seeing and only part of the desired exposure time. Straight pixel-math HSO image for initial work, then discovered the use of NarrowbandNormalization with SHO, and played a lot with that. I'll probably update the HSO image using what I've learned about NBN and star/starless recombinations. Getting NB star colors looking good is an avenue I have to pursue.

Title: Rev2

Description: Learned about NarrowbandNormalization (NBN) being used with SHO. This is an early version, after pixMath combination, SPCC, blurX, noiseX, starX, unlinked STF stretch, and into NBN. Source of info is

Title: SHO final

Description: About as far as I'll go. The background really deepened when I increased contrast using curves. In all of these the need for more time for the Sii data is apparent (other channels could benefit of course, but Sii is sorely lacking).

This is a new "final." I went back to what I saw as a better coloration and use of NBN. Sorry!

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.
