Revision title: The Pillars of Creation and the Stellar Spire in HRGB+HSHO

My first image after taking two years off of astrophotography to build a roll-off roof observatory.

I processed four versions:

Broadband

Ha Luminance - 306x 2min
R - 91x 2min
G - 90x 2min
B - 90x 2min
Total Integration - 19h14m

NBRGB

Ha Luminance - 306x 2min
R - Combination of 306x 2min Ha and 91x 2min R
G - Combination of 120x 2min O3 and 90x 2min G
B - 90x 2min B
Total Integration - 23h14m

Hubble Palette

Ha Luminance - 306x 2min
S2 - 120x 2min
Ha - 306x 2min
O3 - 120x 2min
Total Integration - 18h12m

Broadband + Hubble Palette

Ha Luminance - 306x 2min
S2 - 120x 2min
Ha - 306x 2min
O3 - 120x 2min
R - 91x 2min
G - 90x 2min
B - 90x 2min
Total Integration - 27h14m

The Hubble Palette is always iconic, but I really love how when you use Pixel Math in PixInsight to combine Broadband with Hubble Palette you wind up with really vibrant colors that aren't predominantly yellow.

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.
