IC443 - The Jellyfish Nebula (HST Palette)

IC443, the Jellyfish Nebula (Sharpless 248) is the remnant of a supernova located in the constellation of Gemini. It is about 5000 light years distant and it roughly 70 light years across covering an angular diameter of 50 arc minutes which is about 1.6x the size of a full moon. The large star at the bottom of the frame is Eta Geminorum or Propus.

I had done a bi-color rendition back in October of 2012 and it came out OK, but the SII signal I was missing is very strong in this target and I feel this came out much better using the Hubble Space Telescope (HST) palette.

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.
