LBN 625 - IC 63 - Gamma Cas Nebula - HOO Narrowband - Esprit 120 - ASI1600MM

I shot S, H and O but liked the colors from the HOO combination best.

While I'm not crazy about the finished image, I did feel good about the -process- I used to add RGB stars to my narrow band image.

The first revision is HOO with narrow band stars - mostly white.

The second revision is HOO with stars removed by Straton.

The third and final revision is HOO with RGB stars replacing the narrow band ones.

Process used:

1) PixInsight: Split HOO image into R, G and B channels in PI. Save R, G and B frames.

2) Straton: Remove stars from HOO image R, G and B frames

3) PixInsight: Process RGB (or LRGB) to create RGB image

4) PixInsight: Use NBRGB Combination script to combine RGB image with HOO R, B and B frames

There was very little nebulosity in my RGB image so I was able to just combine it without masking or reducing the nebulosity. If there was a lot of nebulosity I would probably use a star mask so in the NBRGB Combination process I was not "doubling up" on the nebula in the final image.

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.
