A circumpolar star trail stack taken from the Table Mountain Star Party, July 26, 2014, at the Eden Valley Guest Ranch. This is a stack created from 250 frames taken for a time-lapse movie, stacked using Advanced Stacker Actions with "Elastic Stars" effect. Each frame was 45 seconds at f/2.8 with the Rokinon 14mm lens and Canon 6D at ISO 2000.

Sundogs and a solar halo around the Sun, December 19, 2013, shot from home with the Canon 60Da and 10-22mm lens. The halo is caused by ice crystals in the air, in this case very nearby as they can be seen as "stars" sparkling in the sunlight in the sky and in the foreground. This is an HDR stack of three exposures at 2/3rds stop intervals, processed thru Photomatix Pro.

Sunset colours over White Sands National Monument, New Mexico, December 10, 2013. Venus is at left of centre. This is an HDR (High Dynamic Range) stack of 7 exposures at 2/3 stop increments from -2 to +2 EV, processed first with ACR then with Photomatix Pro.

The well-publicized - if not overly publicized! - supermoon (a perigee Full Moon) of November 14, 2016, seen here about 3 degrees above the horizon, rising out of low clouds. The yellow colour is natural, and illuminated the field with a golden glow. However, this is a stack of 4 exposures, from long to short, to create an “HDR” style stack as the longest exposure needed for the clouds blew out the bright Moon. A short exposure was needed for the Moon itself. I took 4 exposures at about 2 stop increments from 1.5 seconds to 1/15 second and blended them not with HDR software but with luminosity

Horizon-to-zenith panorama of the northern winter sky, from Canis Major in the south just above the horizon to Cassiopeia past the zenith at the top of the frame.

This is NGC 457, the ET or Owl Cluster in Cassiopeia, in a stack of images showing the total number of satellite trails recorded over the 36 minutes of total expposure time this night. By coincidence, the trails frame the main subject, but the number of satellites now above us make it nearly impossible to take a long exposure image, certainly at the start or end of a night, without recording at least one satellite trail, if not more, per image. Some of the parallel streaks could be Starlink satellites.

A composite of the Quadrantid meteor shower, on January 3, 2016, in a sequence of images shot over 2 hours from 9 to 11 pm MST from southern Alberta. This is a stack of 14 images, the best out of 600 shot that recorded meteors. The ground and sky comes from one image with the best Quad of the night, and the other images were masked and layered into that image, with no attempt to align their paths with the moving radiant point. However, over the 2 hours, the radiant point low in the north would not have moved too much, as it rose higher into the northern sky.

This is a stack of 14 images, the best out of 600 shot that recorded meteors. The ground and sky comes from one image with the best Quad of the night, and the other images were masked and layered into that image, with no attempt to align their paths with the moving radiant point. However, over the 2 hours, the radiant point low in the north would not have moved too much, as it rose higher into the northern sky.

This is a stack of images demonstrating the number of satellites passing through the field of a wide-field telescope over a little more an hour. The field frames the Coma Berenices star cluster. This is from my home at 51° North, a latitude more prone to seeing satellites lit by the Sun well into the evening, if not all night closer to summer solstice. Most trails are north-south so they are likely NOT Starlink satellites but polar orbiting satellites. Interesting that the trails have different colours, likely from their solar panels or other structures reflecting blue and gold tints.

A “cloud streak” photo made using the same techniques as in stacking star trails only its the clouds trailing, or streaking. I shot this Canada Day, July 1, 2015 from Scotsman Hill overlooking Calgary, awaiting the fireworks. This is a stack of 110 frames, merged with Advanced Stacker Actions using the Ultrastreaks action. Despite the blending, the ~ 8s gap between exposures still led to gaps in the streaks - you’d have to shoot at 1s intervals to eliminate them. To smooth out the gaps I added a duplicate layer for the sky with a Radial Blur filter applied to further streak the clouds. I also

A composite of several exposures to stack images of five Geminid meteors into a wide view of the winter sky with Comet Wirtanen at upper right in Taurus, taken on December 12, 2018. The meteors are shooting away from the radiant point in Gemini near the bluish-white star Castor at left. The Milky Way runs vertically through the frame from Auriga at top to past Orion at bottom.

$Comet Holmes, 17P, taken Nov 1, 2007 on excellent night. Taken with A&M 105mm apo refractor at f/5 with Borg 0.85x compressor/field flattener on SkyWatcher HEQ5 mount. Canon 20Da camera at ISO400. Composite of 4 min, 2min, 1min, 30sec, 15sec, and 7 sec exposures, each exposure being a stack of 3 to 4 identical exposures. Registered and stacked in Photoshop (HDR mode did not produce usable result, so manually composited with sucessively smaller masks to reveal short exposure content around nucleus.

Evening twilight with Venus in the sky, on December 3, 2013 from Massai Point, Chiricahua National Monument, Arizona. This is a 8-frame HDR High Dynamic Range stack to compress the high contrast from the bright sky and dark foreground into one image. Combined with Photomatix Pro. Taken with the Canon 5D MkIi and Rokinon 14mm manual lens at f/8. Some wind has blurred trees. From images _MG_7042 to 7049, taken at 2/3rd stop increments.

The quarter Moon reflected in the waters of Reesor Lake, Alberta in Cypress Hills Interprovincial Park. Taken on July 5, 2014. This is with the 14mm Rokinon lens and Canon 6D at ISO800. This is a high dynamic range stack of 6 exposures from 1/15 to 0.6 seconds taken just before using the camera to take a motion control time-lapse. The Moon was in conjunction with Mars (right of Moon) and Spica (left of Moon) but in the bright twilight they are not showing up here.
