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.
Gamma Cygni nebulosity aka the IC 1318 complex, plus the Crescent Nebula, NGC 6888 at right, in central Cygnus, taken on a superb night from home July 30, 2011. This is a stack of 5 x 12 minute exposures at ISO 800 with the filter-modified Canon 5D MkII and the Borg 77mm f/4.3 astrograph lens (300mm focal length), and using the IDAS V3 nebula filter. Orientation is tilted off true north at top (my usual orientation) to take in NGC 6888 and the little blue reflection nebulas at upper left.
