The Jellyfish Nebula, IC443, is a supernova remnant. This is a fairly large object located at the feet of the Gemini twins, not far from M1, the Crab nebula. This image is the result of 15 hours of exposures in the H-alpha and OIII emission bands with the TOA-150 and STL-11000xm. Astrodon narrowband filters make imaging from the light-polluted sea-level city possible. They do nothing for the clouds and rain, though.
