Description

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.
