A 240° panorama of a not very active display of Northern Lights to the north (left of centre), then sweeping around to the south (at right) and the winter stars of Orion and Canis Major. Sirius is bright and in some cloud, accentuating its size and colour. Leo is rising at centre. The Big Dipper and Ursa Major are left of centre. The Milky Way appears at far left, in the area of Perseus and Cepheus, and again at far right through Monoceros and past Orion and Canis Major. The aurora display the characteristic green and red curtains from oxygen, but there is also a dim red curtain at left (northwest) and at centre (east) south of the main curtain and separated. It looks like a dim Steve arc but this was not visible to the eye and never became well formed or bright. This is a stitch of 8 segments with the 14mm Sigma Art lens, at f/2 for 13 seconds each, and Nikon D750 at ISO 3200. Stitched with Adobe Camera Raw. Taken from home January 13, 2018. The constellations are distorted slightly by the panorama projection and warping. I began a time-lapse after this, but clouds rolled in from the northwest.
A moonlit nightscape of the badlands loop road in Dinosaur Provincial Park, arcing off toward the Big Dipper in the northern sky. Vega is setting at far left. Polaris is at top centre. Light is from the 8-day waxing Moon. A stack of 6 x 15-second exposures mean combined to smooth noise for the ground, and a single 15-second exposure for the sky, all at f/2.5 with the Rokinon 14mm lens and Canon 6D MkII at ISO 2000.
The winter stars and constellations rising over the moonlit sagebrush and badland hills of Dinosaur Provincial Park, Alberta, on November 27, 2017. Orion is at centre; Taurus above, and Gemini at left. Sirius is just rising above the hill in the distance at centre. A good illustration of the Belt of Orion pointing up to Taurus and down to Canis Major and Sirius. This is a stack of 10 x 15-second exposures for the ground, mean combined to smooth noise, and a single 15-second exposure for the sky, all with the Rokinon 14mm lens at f/2.5 and Canon 6D MkII at ISO 1600, with LENR on. I applied a 3-pixel Gaussian blur to a duplicate sky layer, blended with Lighten, to add an “Orton effect” style glow to the stars.
