The Jellyfish Nebula

© 2014 Klaus Brasch

IC-443 (aka the Jellyfish Nebula) is the remnant of a supernova explosion in Gemini thought to gave taken place between 3,000 and 30,000 years ago and is approximately 5,000 light years from us. Though tough to spot visually except with large telescopes and very dark skies, it makes for a beautiful photo target. I combined this one in Registar using images taken with my TMB-92, AP-155 refractors and an older image taken with a C-11 HD. All were shot with a modified Canon 6D and an IDAS LPS V4 narrow band pass filter. Cumulative exposure is about 30 minutes at ISO 3200.

IC 443

"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 plan 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 star CXOU 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.."
