California Nebula with Bill Blanshan and Russ Croman Scripts HOO with OSC

NGC 1499 is an emission nebula that has a very low surface brightness and is difficult to observe visually. I have never seen it visually [bucket list].

The California Nebula contains a hot blue-white star named Menkhib (also designated Xi Persei), by far the brightest star in this image. Menkhib is one of the hottest stars visible in the night sky.

Menkhib is part of an association of hot stars that were born only a few million years ago. These luminous stars are lighting, heating and ionizing the nebula.

I processed this with the same data as my other image taken with the AT60ED [see other images]. I used Bill Blanshan's scripts with HOO processing / masks and Russ Croman's BlurX and Noise X. These methodologies have transformed post-processing for me.

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.
