Circumpolar star trails over a grand old barn in southern Alberta, on a fine spring night, May 23, 2018. Illumination is from the waxing gibbous Moon to the south. This is looking north to Polaris at top right. A thunderstorm is on the northern horizon with a lightning bolt as a bonus.
Mars (at left) and the galactic centre area of the summer Milky Way low over the southern horizon at Writing-on-Stone Provincial Park, Alberta, on June 8/9, 2018. Sagittarus is at centre, with Scorpius at right. The Messier 6 and 7 open star clusters are just above the horizon at centre, just right of the Sweetgrass Hills on the horizon in Montana.
The rising of the Full Moon on Easter eve, Saturday, March 31, 2018, on a very cold night with lots of snow still on the ground in Alberta. So this is more a winter Moon than a spring one. This is the 'paschal' Moon ' the one that defines the date of Easter, being the first Full Moon after the vernal equinox. The first Sunday after that Full Moon, in this case the next day, is Easter Sunday.
A horizon-to-zenith panorama of the winter consellations on a March evening as they set into the southwest. Orion is at bottom centre, with his Belt pointing down to Canis Major and up to Taurus. Gemini and Auriga are at top, in this case near the zenith overhead. The bright star clusters, M44, the Beehive, (at left) and M45, the Pleiades, (at right) flank the Milky Way. M45 is embedded in the Zodiacal Light. The star clusters M35 in Gemini and M41 in Canis Major are also visible as diffuse spots, as are several other star clusters. A couple of satellite trails are visible.
A composite of the August 21, 2017 total eclipse of the Sun, showing the second and third contact diamond rings and Baily's Beads at the start (left) and end (right) of totality, flanking a composite image of totality itself. The diamond ring and Baily's Beads images are single images.
NGC 7000, the North America Nebula, with the Pelican Nebula, IC 5067, at right, in Cygnus, taken from home November 21, 2016 as part of testing of the Explore Scientific FCD100 102mm apo refractor. This is a stack of 5 x 6-minute exposures at f/7 with the ES field flattener, and at ISO 1600 with the filter-modified Canon 5D MkII. Star diffraction spikes added with AstronomyTools actions.

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.
