California Nebula OSC+Ha (NGC 1499/Sh2-220)

The California Nebula is a faint visually but bright Hydrogen alpha emission nebula with medium length exposures in the constellation of Perseus within our Milky Way. It is approximately 1000 light years from earth and literally in our cosmic backyard.

I used a new technique capturing the data and assembling the data. I captured RGB using my ASI 294 MC and then collected Ha using my ASI 1600. I proceeded to color enhance the red channel in the RGB image using pixel math to add in Ha data and then recombined it with the original green and blue channel for an enhanced RGB. The Ha alpha data was also used to add 1/3 weighted luminance to enhance more details.

So really it is a Lum (Ha) + (Red+Ha)GB.....good grief!

I am pleased how it turned out, but definitely welcome feedback.

There are a few cosmetic correction I will work on later with more time.

I find that so many images of this nebula are too over done on the florescent red color, so I tried to strike a balance. I am sure I will probably thoroughly dislike it when I look at it again tomorrow.

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.
