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.
Comet PanSTARRS (C/2017 S3) on the night of July 9/10, 2018 with it low in the northeast from my site in Alberta. This is a stack of three 4-minute exposures at ISO 3200 with the Canon 6D MkII on the Asrtro-Physics 130mm apo refractor at f/6. If I had been more watchful I could have re-framed it better to include the star cluster Tombaugh 5 at upper right.
Scorpius and Sagittarius rising, with Scorpius coming up on its side, as seen from New South Wales, Australia, April 2, 2016. Mars is the brightest object left of Antares in Scorpius, with fainter Saturn below the reddish pairing of Mars and its rival Antares. The cyan-colored blob at lower left above the trees is Comet Linear/252P, which passed close to Earth the previous month. Many nebulas and clusters are visible along the Milky Way around the Galactic Centre in Sagittarius, which is rising here. This is a stack of 5 x 3-minute exposures with the camera on the iOtron SkyTracker, all at f/2.2 with the 35mm L-Series Canon lens and filter-modified Canon 5D MkII at ISO 1600. The ground comes from one other exposure taken imediately after the tracked exposures but with the tracker motor off, and exposed for 8 minutes at f/3.2 and at ISO 640 for lower noise in the sharp, brightly exposed foreground.
