IC 443 (GEM) JellyFish Nebula - A JellyFish floating in space …

What’s in the picture(s) - https://en.wikipedia.org/wiki/IC_443
Quote: “IC 443 (also known as the Jellyfish Nebula and Sharpless 248 (Sh2-248)) is a galactic supernova remnant (SNR) in the constellation Gemini. On the plane of the sky, it is located near the star Eta Geminorum. Its distance is roughly 5,000 light years from Earth.

IC 443 may be the remains of a supernova that occurred 3,000 - 30,000 years ago. The same supernova event likely created the neutron starCXOU J061705.3+222127, the collapsed remnant of the stellar core. IC 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.

IC 443 is an extended source, having an angular diameter of 50 arcmin (by comparison, the full moon is 30 arcmin across). At the estimated distance of 5,000 ly from Earth, it corresponds to a physical size of roughly 70 light years."

What was the experience
This DSO was also part of the series of objects for which I collected data over multiple nights in early March. Ì collected 7h on this object, a bit less compared to what I would’ve wanted, but the full moon was nearing the object, and since then it has been cloud season (instead of Galaxy season)

Standard HOO processing, using a blend of fornax-formula and straight hoo, on this one, with some tweaks from the GAME script to reduce the halos around the 2 big stars. Stars processed separately, but I'm not too happy with their outcome, something I still need to improve upon. I feel I lost some of the background nebulosity in this area while neutralising the background. A bit longer integration time could've probably prevented this.

Happy with the fine details of the filaments of this supernova remnant … 😎

How it was done
Scope: TS94 APO (FL 414mm)
Mount: EQ6-R Pro
Camera: ASI2600MC Pro
Photons: 20220305-0308 L-Enhance 180s 141x 07:03
Processing: PixInsight (Mac)

What have I learned from this
My HOO-processing has become a bit of a ‘business as usual’, but I continue to search for new techniques, new functions, new processing … to further sharpen, improve the colour balance and the overall quality of the image …

Clear Skies everybody! 🤩✨🔭
