California - The Golden State

This is my latest November project -- The California Nebula (NGC 1499). I collected 18h 48m of Ha, Sii, and Oiii data from my backyard and from a relatively dark sky (Bortle 3/4) near Julian, CA over Thanksgiving weekend.

I've always thought California was an interesting target, but I've never given it a lot of attention, and my previous attempts have never revealed much structural details. I was hoping to get 25+ hours but clouds have been the rule for the last week, and I got impatient and decided to process the data that I have. I've usually neglected Sii (in most of my targets) but I was surprised to see how strong of a channel Sii is in the California. This was processed with the Forax channel mapping strategy in Pixinsight: I really liked the way the golden flames and the wisps of blue on the inland side turned out, but I struggled to decide with the bold saturated golden look vs a more muted color scheme. Sticking with this one for now

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.
