IC 443, a supernova remnant in Gemini (aka the Jellyfish Nebula) and associated nebulosity such as IC 444 and LDN 1565, plus the Messier open cluster M35 at right, with its companion cluster NGC 2158 below it. This is a stack of 12 images, with the TMB 92mm and Borg 0.85x flattener for f/4.7, and filter modified Canon 6D at ISO 800. 8 shots were 6 minutes and 4 shots were 8 minutes.
