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.
The supernova remnant IC 443 in Gemini near the stars Mu (left) and Eta (right) Geminorum. Slight haze passing thru on some exposures added the star glows. This is a stack of 10 x 6 minute exposures with the 92mm TMB apo refractor at f/4.4 with the Borg 0.85x field flattener/reducer and the filter-modified Canon 5D MkII at ISO 800. Star spikes added in Photoshop with Astronomy Tools actions.
NGC 6888 and IC 1318 nebulosity in Cygnus, with Canon 20Da and TMB 92mm f/5.5 apo refractor with Borg 0.85x reducer/flattener at f/4.6, for stack of 4 x 15 minute exposures at ISO400. Taken on a superb night from home, Oct. 1, 2008.
