Image Details:

This is my version of IC 443, a supernova remnant located in the constellation Gemini, also known as the Jellyfish Nebula. It is believed to be the result of a supernova explosion that occurred approximately 5,000 to 30,000 years ago. The remnants of the exploded star have expanded and now span about 70 light-years across.

It had been cloudy in my location for greater than 6 weeks so I was delighted to be able to get enough time to do this target justice.
