The waxing crescent Moon in the sunset sky over the Rocky Mountains from the Rothney Observatory on May 27, 2017 at the monthly Open House. Cars are parked along the road at right.
The summer Milky Way in Sagittarius and Ophiuchus to the south along the horizon at 3 am on a May morning with the sky brightening and turning blue from dawn already. This was from my backyard at home in Alberta at latitude 51° North. The image also serves as a demo of an exposure time (45 seconds) exceeding the “500 Rule” and introducing some trailing. This was with the 35mm lens. The ground is a stack of 4 exposures, the sky from just one exposure. Also serves as a demo of Stack Modes for Workshops and articles. Shot as part of testing the SAM tracker.
Orion setting in deep twilight sky with stars in abundance but the sky still deep blue, from Australia with Orion “upside down.” The Saucepan asterism popular in Australia is visible here, made of the Belt stars, and stars in the Sword and the star to the left of the bottom star in the Belt here. This is a stack of 4 x 20 second exposures for the trees to smooth noise and one 20-second exposure for the sky, all untracked with the 35mm lens at f/2 and Canon 6D at ISO 1600. Taken from Tibuc Gardens Cottage, Coonabarabran, Australia.
