IC 443 Supernova Remnant (92mm 5DII).jpg

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.
