IC443 - The Jellyfish Nebula 2025

The past few weeks we finally had some clear nights. Gemini and Monoceros constellations are visible for only a couple of hours before being blocked by trees in our backyard. So I put both rigs to work gathering data on IC443, the Jellyfish Nebula, and the Cone Nebula (hopefully I can gather a bit more). Its distance is roughly 5,000 light years from Earth.

 

IC 443 is a galactic supernova remnant in the constellation Gemini.

 

I processed this image in HOO, incorporating SII data using Adam Block Gilding Method. I think I ended up with a nice Red/Orange color.
