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.

The waning gibbous Moon approaches the star Aldebaran at an occultation on the morning of September 12, 2017. This is a multiple exposure composite of the ingress phase that occurred before sunrise, with the Moon from the final exposure and the star from exposures taken at 4-minute intervals prior to that last exposure. For the actual ingress I switched to HD movie to shoot a video of the event.
