IC443 - A Jellyfish glides through the space

Revision title: Processed in Classical HOO

IC443 has been on my list of objects to photograph for a long time. Also known as Jellyfish it is a galactic supernova remnant that interacts with the surrounding molecular clouds. I was very excited about how many structures became visible in the image. So, have a closer look on the full resolution image to discover them.

In the lower left corner some fringes of IC444 become visible. In order to depict IC444 completely, I plan to create a mosaic next season. So stay tuned.

The frames themselves were taken with the great Optolong L-eXtreme dual-narrowband filter. The processing in PixInsight uses synthetic SHO color channels, as I had already used for the Lion Nebula.

I hope you like it! I look forward to your feedback and comments.

Description: Here is a HOO based processing of the Jellyfish Nebula. Decide for yourself which version you like better. My personal favorite is the synthetic SHO-based version.

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.
