The loose open star cluster Collinder 140 in southern Canis Major, a zig-zag line of stars (which looks like a letter J visually through binoculars) just left of centre here. The orientation is along the Milky Way here, so north is at right, not at top. This is a stack of five 2-minute exposures with the Canon L-series 135mm lens at f/2.8 and Canon 7D at ISO 1250. The field simulates a binocular field of roughly 7°.
A wide-field image of the Coma-Virgo Galaxy Cluster including the Messier galaxies around the star 6 Comae at top right, down to the galaxies of Markarian’s Chain at bottom left, including several other Messiers. The field is about 4 degrees high and 6 degrees wide. This is a stack of 5 x 8-minute exposures through the SharpStar 76mm EDPH refractor and with the SharpStar flattener/reducer for f/4.5, and with the Canon EOS Ra at ISO 800. An additional exposure taken through light cloud layered in added the star glows. Clouds prevented more exposures.
