This is the 3rd time trying this object, always something that has invalidated my attempts in the past, nice to finally get a presentable image out of this data set.

These are 2 interpretations of this classic object, one in the Foraxx palette using the excellent ForaxxPaletteUtility script in Pixinsight, by Paulyman Astro, and one using the NBColourMapper script in PixInsight - both then further color tweaked to taste. I do not usually post 2 versions of the same data, but in this case I felt each version accentuated different parts of the target object. The Foraxx palette seems to give a pretty clean delineation between the 3 classic NB channels, where as the 2nd version, where I tried to mimic a more 'RGB-like' result, shows off some of the subtler details in some of the Hα regions a little more clearly IMHO. It was a hard choice to pick which to mark as my final version, but for me it is the Foraxx version. I am interested to hear other opinions on which is preferred for anyone who cares to share their opinion. That and any other comments, critiques, or questions are most welcome, and thanks for looking.

The Jellyfish Nebula is a supernova remnant (SNR) that is thought to be located approximately 5,000 light years distant. The supernova event is estimated to have occurred between 30,000 - 35,000 years ago. The image also contains the blue reflection nebula IC 444.

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.
