Not IC 3104: But a Pig's Ear?

OTA: PW17
Camera: QHY 600 M
Observatory: Deep Sky West
Date of Capture: Dec '23
Date of Processing: Jan '24

Exposures:
R: 6 x 300 sec
G: 5 x "
B: 5 x "

Total Exposure time: 2.4 hours
Image Width: 41.4 arc-minutes

Processing Tools:
1.   Commercial: PixInsight, Topaz, Photo Director 365, Luminar Neo
2.   Pixinsight Addons: NoiseXTerminator, BlurXTerminator, StarXTerminator
3.   My Scripts: AC_Restar, Subframe Weighting Tool (Excel w/ J. Hunt)

Target Description:
"Not IC 3104," let me explain. IC 3104 was the designation on the data set, but, in fact, IC 3104 is a faint galaxy lying beyond the bottom of this image. The Bright star has the designation TYC9416-1274-1, and the overall nebula surrounding this star and extending beyond this image does not appear to have a specific name…just "the dark nebula in Chamaeleon" (the constellation name is "Chamaeleon.")

I do like the detailed structures immediately around the bright star, and, overall, it's not an unpleasing image, although it arguably has not become a "silk purse."

Processing Description:
With a faint dark nebula, a mere 2+ hours of exposure, and abundant satellite trails, the challenge of making a silk purse from this pig's ear was none trivial! Despite using SKill to suppress the trails, some left a scar that made it to the final image, where I suppressed them further.

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.
