A telescopic closeup of Comet Lovejoy (C/2014 Q2) on January 19, 2015. I shot this from near Silver City, New Mexico, using a TMB 92mm apo refractor at f/4.4 and using a Canon 6D at ISO 1600 for a stack of 4 x 5 minute exposures. The ion tail is primarily from a single exposure to minimize blurring from the comet's motion relative to the stars. The rest of the image is from the stacked combination to minimize noise.

Comet NEOWISE (C/2020 F3) reflected in the still waters this night of Crawling Lake in southern Alberta. A dim aurora at right colours the sky magenta. Lingering twilight colours the sky blue. A meteor or more likely a flaring satellite appears at right and is also reflected in the water. Even in this short exposure, the two tails ' dust and ion ' are visible. This was July 20, 2020.

This is Comet NEOWISE (C/2020 F3) over the Horseshoe Canyon formation near Drumheller, Alberta on the night iof July 10-11, 2020, taken about 2 a.m. MDT with the comet just past lower culmination with it circumpolar at this time. Warm light from the rising waning gibbous Moon provides the illumination. The comet's faint blue ion tail is just barely visible even in the moonlit sky and low altitude. The glow of summer perpetual twilight at latitude 51.5�8 N still colours the northern horizon despite this being close to the middle of the night.

Another incredible sky this night!
