JellyFish Nebula (IC443) in natural colors

Posted on March 7, 2022May 31, 2022

New apporach to this popular object after five years from my first image.

IC 443 (also known as the Jellyfish Nebula and Sharpless 248 (Sh2-24) is a galactic supernova remnant (SNR) in the constellation Gemini.
ts 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.
C 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.

This images is a result of a 65 hours of integration time using rgb and narrow band filters.

One learning on that image is that I am really happy with this new tube used, a Takahashi Epsilon 160-ED did all the captures and this is the second published result.
