The Jellyfish Nebula, IC 443, at left near the star Eta Geminorum at left. IC 443 is a supernova remnant. At upper ight is the bright open star cluster Messier 35. The smaller and fainter star cluster below M35 is NGC 2158. M35 is 2500 light years away but NGC 2158 is 16,500 light years away. This is a stack of 10 x 6-minute exposures with the 92mm TMB apo refractor at f4/4 with the Borg 0.85x field flattener/reducer and the filter modified Canon 5D MkII at ISO 800. Taken from New Mexico.
The area of sky around the star cluster Messier 35, at top in Gemini, with the supernova remnant IC 443 below, and the Monkeyhead Nebula, IC 2174, in Orion at bottom. This is with the 200mm Canon lens to frame a binocular field of view, and taken with the filter-modified Canon 5D MkII camera at ISO 800, for a stack of 9 x 2-minute exposures and through the NISI Natural Night filter to help bring out the nebulas. On the iOptron Sky Guider Pro. Taken from home Feb 20, 2020. The modified camera did a better job at recording the red nebulas than the stock 6D MkII did in shots taken the night before for comparison.
Open cluster M35 in Gemini and nearby nebulosity IC 443 (Jellyfish Nebula) bottom left of cluster and NGC 2174 below cluster. This is a stack of 5 x 4 minute exposurs with Canon 5D MkII at ISO 800 and Canon 135mm lens at f/2.8. Taken January 6, 2011. Field of view simulates binocular field.
