My astronomy photography is available on the Astrophotography page.
The passage of the International Space Station (ISS) over Calgary, Alberta, was recorded on the evening of April 7, 2019, at 9:20 PM MDT. One-second exposures were recorded every two seconds with a Nikon D750 at ISO 800 and Sigma Art 14mm DG HSM lens at f/5.6, then processed and combined in Lightroom and Photoshop.
This was the last visible passage of the ISS from my location, so the circumstances were poor. I have added an arrow to the video to show its emergence from the twilight glow.

A 65-minute time-lapse sequence of twilight on the evening of April 7, 2019, from Calgary, Alberta. Images were taken from one hour after sunset until shortly after the end of astronomical twilight. The individual image frames were exposed at aperture-priority auto, at ten-second intervals with a Nikon D750 at ISO 800 and Sigma Art 14mm f/1.8 DG HSM lens, then processed and combined in Lightroom and Photoshop.
A one-hour time-lapse sequence of Orion setting, as recorded on the evening of April 2, 2019, from Highway 68, about 400m south of the Sibbald Creek Trail exit on the Trans-Canada Highway, Alberta. Ten-second exposures were recorded every 15 seconds with a Nikon D750 at ISO 800 and AF-S Nikkor 35mm lens at f/1.8, then processed and combined in Lightroom and Photoshop.
A one-hour time-lapse sequence of Orion setting, as recorded on the evening of April 2, 2019, from Highway 68, about 400m south of the Sibbald Creek Trail exit on the Trans-Canada Highway, Alberta. 20-second exposures were recorded every 25 seconds with a Nikon D750 at ISO 800 and Sigma Art 14mm f/1.8 DG HSM lens, then processed and combined in Lightroom and Photoshop.
The Zodiacal Light is the prominent band of light extending from the lower right to the center of the frame.
The passage of the International Space Station was recorded on the evening of April 2, 2019, at 10:20 PM MDT. My observing site was on Highway 68, about 400m south of the Sibbald Creek Trail exit on the Trans-Canada Highway, Alberta. One-second exposures were recorded every two seconds with a Nikon D750 at ISO 800 and Sigma Art 14mm f/1.8 DG HSM lens, then processed and combined in Lightroom and Photoshop.
The passage of the International Space Station over Calgary, Alberta, was recorded on the evening of March 29, 2019, at 8:54 PM MDT. 1/15-second exposures were recorded every second with a Nikon D750 at ISO 800 and Sigma Art 14mm f/1.8 DG HSM lens, then processed and combined in Lightroom and Photoshop.
A 60-minute time-lapse sequence of twilight on the evening of March 28, 2019, from Calgary, Alberta. Images were taken from one hour after sunset until shortly after the end of astronomical twilight. The individual image frames were exposed at aperture-priority auto, at ten-second intervals with a Nikon D750 at ISO 800 and Sigma Art 14mm f/1.8 DG HSM lens, then processed and combined in Lightroom and Photoshop.
At 22 seconds into the video, the International Space Station appears and then moves off the top of the frame.
The International Space Station (ISS) transited the Sun on December 22, 2018, at 2:50:48.2 PM MST, as seen from Calgary. I shot high-definition video at 60 frames/second with a Nikon D750 at ISO 100 and 1/1000 second exposure with the Meade 4" f/10 Schmidt-Cassegrain telescope and solar filter.
The sun was only 10° above the horizon and seeing conditions were poor. The ISS was 1466 km away, so little detail of its shape is evident here. The processed video has been slowed down by a factor of two.
This color-corrected photomontage (showing every fifth frame from the original video) was created with Lightroom and Photoshop.
A 60-minute time-lapse sequence of twilight on the evening of December 16, 2018, from Calgary, Alberta.
