NGC 2359 Thor's Helmet HOO 2022 v. 2023 Comparison Edit

I was editing a M42 Mosaic and got to a frustration point and decided give a redo edit of Thor's Helmet from last year with my processing and tool improvement. Definitely take a look at image B for the full resolution new edit. I would love to hear any positive or negative feedback.

The initial image is the same data I collect a year prior processed last year and this year. Last year's version was a standard HOO palette compared to this years was H (H*.3+O) (H*.3+O). I have also attached the comparison from my first attempt at this beautiful object from 3 years prior.

The improvement with BlurX and Noise X really improved otherwise terrible stars and added a substantial depth to the image. Also, the 2nd gen star removal tools really allow so much further processing latitude with the image.

NGC 2359, is approximately 15,000 light years away in the Milk Way in the Constellation Canis Major.

The bright Wolf-Rayet Star in the middle of the structure is 280,000 times brighter than our Sun, 16 times more massive, and 1.41 times larger with a surface temperature of 112,000 K (201,140 degrees Fahrenheit.

The sun's surface temp is a meager 5,778 K (9947 degrees Fahrenheit).

The main helmet/bumble is molecular debris that is ionized and shocked by the center bright star. The solar winds measure approximately 1500 m/s.

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.
