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.

This is with the 200mm Canon lens to frame a binocular field of view, and taken with the standard Canon 6D MkII camera at ISO 800, for a stack of 16 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 19, 2020. The stock camera did a pretty good job recording the red nebulas but not as good as the filter-modified Canon 5D MkII did on shots taken the next night 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.
