IC 443 - 30 hrs On Top of the Jellyfish

The Jellyfish Nebula is the remnant of a supernova interacting with local interstellar molecular clouds located at a distance of about 5,000 ly. The entire nebula is quite a large complex that extends over roughly one degree. At one edge, lies a neutron star that was formed after the supernova event. The interaction of the rapidly expanding gas shell with the surrounding dust clouds created the complex web of turbulent material visible in this image. Energy produced by the deceleration of the leading edge of the blast wave is the source of maser radiation that has been detected from this object. The prominent dark lane passing through the lower/right portion of the image is likely due to a molecular cloud in front of the nebula along our line of sight.

The narrow band data for this image was captured over the period of about a month using my remotely operated C14 Edge located at DSW outside of Santa Fe. This image is presented in the Hubble SHO palette and is made up of a subset of 20 minute exposures selected from a total of 87 hours of exposure. Given the large amount of data, I was able to pull out a fair amount of detail in the dust clouds and it is interesting to examine it in detail on a full screen.

I often miss one thing or another in my processing so as always, C&C is more than welcome. Maybe someday I'll finally get this thing figured out... :-))

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.
