NGC1499 California Nebula, HaRGB

Came up with my own way doing final combination of Ha and RGB in Photoshop after I did initial processing in PixInsight. Basically, a normal base layer of just the Ha mixed into the red channel. Then a starless luminance layer to bring back in detail in the nebula, and finally a "screen" blended stars only layer on top. I'm sure others have used this technique, but I stumbled across it on my own after some failed attempts to keep good star color after blending the lum.

Thanks for looking!

Description: After feedback from Alan Jordan (cloudynights) and others, I minimized the red halos in this new version. Trying to get to the bottom of what is causing those. Something is weird about the alignment and the focus with all my red frames with this particular setup so far. :(

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.
