The periodic comet 21P, Giacobini-Zinner in Auriga on September 4, 2018 as it passed east of the triangle of stars at right called The Kids, near Capella. The comet is distinctly cyan and red. It was plainly visible in binoculars at about 7th magnitude. Some faint HII emission nebulosity, including a couple of Sharpless nebulas, permeate the field at left. This is stack of 3 x 4-minute exposures with the 77mm f/4 Borg Astrograph and filter-modified Canon 5D MkII at ISO 1600. Guided on the stars - the comet did move a little between exposures but not enough to blur its image much at this focal length. Taken from home with the field low in the northeast but on a fine night. Diffraction spikes added with AstronomyTools.
