Jellyfish and the nearby Neighborhood HOO + Quadband Stars

I wanted to get this image out of the way as halfway through the imaging, I realized I wanted to frame this project differently. This one had been pretty annoying to capture as whenever this target was up, it was starting to get cloudy or there were already pesky high clouds. This made it a huge pain to clean out those datapoints.

Processing steps:

Stack in ASTAP
Remove backgrounds in GraXpert
Bring images to Affinity
Stretch the Quadband data then export
Use Starnet 2 CLI on the quadband data to get the stars
Split the color channels on the HaOiii Dualband image. Stretch then export each monochrome layer.
Use Starnet 2 CLI to extract the stars from the monochrome images and bring them back to Affinity
Recolor the images G as Oiii -> G and B. R as Ha -> R.
Combine the images together along with the stars after some adjustment of the vibrance

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.
