Jellyfish Nebula IC443

The Jellyfish nebula was a more difficult processing experience than my recent Cone nebula. The SNR itself is very bright and clear, but more integration time probably would have improved the surrounding gas and more faint background regions. I tested quite a number of false color patterns, ultimately settling on using the Foraxx palette as a base for my primary image upload. Foraxx essentially produced a solid orange scene, so I used some additional masking to try to bring out more of the subtlety as best as I could. I am uploading versions based on SHO and HOO too (each with some selective re-coloring to improve contrast); each has some interesting elements, but I found myself liking the Foraxx one the most out of all the ones I created.

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.
