Orion and Canis Major over Lake Annette, in Jasper National Park, with Sirius and other stars reflected in the waters. Orion appears over Whistler peak, illuminated in part by lights from the Jasper townsite. I shot this on the morning of October 25, 2015, as the sky was brightening with dawn twilight. The exposure was 25 seconds at f/2.8 with the 24mm lens and at ISO 3200 with the Canon 6D. The camera was untracked, on a fixed tripod. No filter was employed - the fuzzy star glows come from high haze in the sky that morning.
The ISS (International Space Station) rising out of the west over the Red Deer River, near the Atlas Coal Mine site (the source of the streetlight here), in the evening twilight, October 10, 2015. This is a single 30-second exposure at f/2.5 with the Sigma 24mm lens and Nikon D750 at ISO 1600.
The waning crescent Moon, lit by Earthshine, with four planets on the morning of October 9, 2015, with the planets from bottom left to top right: • Mercury, just above the horizon between the low cloud bands, at lower left • Jupiter, bright at centre • Mars, reddish and above Jupiter • Venus, brightest at upper right and in some thin cloud. The bright star Regulus in Leo is above and to the left of Venus. This is a blend of four exposures: a long 4-second exposure for most of the sky and ground and shorter 2, 1, amd 1/2 second exposures for the bright twilight area and around the Moon and Venus, to prevent those areas fro being blown out. Blending is with masks, not HDR. All with the Canon 6D at ISO 400 and 50mm Sigma lens at f/2.5
