Description

To wait out a solid overcast I reprocessed an image from January of 2016 that was originally Ha only. I find large nebulae very tricky to process.

IC 443 (also known as the Jellyfish Nebula) is a Galactic supernova remnant in the constellation Gemini. 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. IC 443 is one of the best-studied cases of supernova remnants interacting with surrounding molecular clouds.

The remnant is evolving in a rich and complex environment, which strongly affects its morphology. Multi-wavelength observations show the presence of sharp density gradients and different cloud geometries in the surroundings of IC 443.
