ISS with STS118, pass on August 15, 2007. Single long exposure of 134s at f/4.5 with 10-22mm lens at 10mm and Canon 20Da at ISO100. Image underexposed (should have set lens to f3.5) but brought out detail in Raw conversion.
Pass of Space Station with Space Shuttle attached (STS118, with Dave Williams and Barbara Morgan aboard), taken Saturday, August 11, 2007 from Cypress Hills, Saskatchewan, from site of Saskatchewan Summer Star Party. Composite of ten 15-second exposures at 1-second intervals at ISO1600 and f/3.5 with 10mm lens on Canon 20Da camera, stacked with Lighten mode in Photoshop, and with 1-sec gaps in ISS trail filled in with cutting and pasting trail image from previous layer. Shows ISS/Shuttle approaching and brightening as it nears, and also climbs above atmospheric extinction caused by forest fire smoke from Montana fires.
The SpaceX Starlink satellite train from the first group of 60 satellites launched, captured May 26/27, 2019 from home in southern Alberta as they traveled through the Big Dipper high overhead at approximately 12:55 a.m. May 27, 2019. Most of the few dozen satellites were faint but on this pass 4 were quite bright, and easily naked eye, and similar to the Big Dipper stars in magnitude. Polaris is at lower right at the end of the Little Dipper handle. This is a frame grab from a 4K video at ISO 52000 with the Sony a7III and Canon 24mm lens at f/1.4. I stacked 8 frames to smooth noise but the satellites themselves are from one frame to keep them point like. Taking a longer exposure still image at a lower ISO was not an option here as the moving satellites would have blurred into a streak looking much like any single satellite trail. So taking a video at an ultra-high ISO speed, then extracting still frames was the method of choice though it produces a noisy image.
