CTB1 and King 12 - Crown & Sceptre - Composition LRGB and HaOIII

Revision title: Used re-processed CTB1 from 2016

Captured around 6hrs of L and RGB for King 12 in Cassiopeia making sure I covered the area where - Abell85 / CTB1, the so called Garlic Nebula - is. I was planning to add Ha and OIII using the Moravian C5 but with the weather turning for the worse, I decided to use my own data from 2016/17 for CTB1 for which I had used a Moravian G4 and then do a composition.

Check the first version here for the G4 data aligned to the larger field of the C5. L, RGB taken using the tandem setup: 152mm f/7.5 StarFire EDF and 92mm Stowaway.

Original version from 2016 in HaOIII with RGB stars: https://www.astrobin.com/278496/B/

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.
