Hi,
Been a while since I've posted a new image, been cometing.
IC 443 (also known as the Jellyfish Nebula and Sharpless 248 (Sh2-248)) is a Galactic supernova remnant (SNR) in the constellation Gemini.
This is quite large with a low surface brightness.
ISO 6400 really helped on this, here's a previous effort.
