A 180° panorama of the rising Full Moon and twilight colours over the badlands of Dinosaur Provincial Park, Alberta on December 29, 2020. This was the "Cold Winter" Moon of 2020. The view is overlooking the Red Deer River valley. I shot this panorama from the Park's entrance gate viewpoint. The image is a 14-segment panorama with the 50mm Sigma lens at f/4.5 and Canon EOS Ra at ISO 100, stitched with Adobe Camera Raw. The original is 34,000 pixels wide.
Jupiter and Saturn, on the eve of their rare "Great Conjunction," shot here on December 20, 2020 from Dinosaur Provincial Park, Alberta. The two planets are very close here, only 8 arc minutes apart, just 2 arc minutes more than at closest approach the next night (which was cloudy!). Even so, they are resolved in this image with an 85mm lens, and were easily resolvable to the naked eye. Some of the moons of Jupiter are visible, particularly Callisto and Ganymede to the left of Jupiter. This was a superb night at the Park, with perfect skies and a mild temperature of only 0° C and no wind or frost. Illumination is from the twilight but also moonlight from the waxing quarter Moon off frame to the upper left. This is a blend of tracked (for the sky, to prevent star trailing) and untracked (for the ground) exposures: 7 x 30 second exposures for the ground (to bring out foreground detail) at f/2.8 and 5 x 8-second exposures for the sky at f/4, all at ISO 400 and with the Rokinon 85mm lens and Canon EOS Ra camera. The camera was on the Sky-Watcher Star Adventurer 2i tracker. Stacking the tracked shots blurred the moving clouds and smoothed noise. Stacking the ground reduced noise. I shot this well past traditional "blue hour" when there was still colour in the sky to the camera, but the sky was dark enough to show stars, and the ground was beginning to light up with moonlight, highlighting the snow and ice patches.
This is an impressive area of sky rich in bright and dark nebulas and open star clusters in Sagittarius and Serpens. This is closeup of the Small Sagittarius Starcloud, aka Messier 24, at bottom right, with the field extending north to include the nebulas M17, the Swan Nebula, and M16 at top right, the Eagle Nebula. Between M17 and M24 is the small star cluster M18. Patches of red and blue nebulosity at bottom right below M24 are IC 1283 and the blue reflection nebulas NGC 6589 and 6590. The prominent dark nebula at the right (west) edge of the Starcloud is Barnard 92 with its lone star embedded in it, with smaller B93 above it. At the left are the star clusters M25 (bottom) and NGC 6645, with the large dark nebula B312 above. This is a stack of 3 x 6-minute exposures with the William Optics RedCat 51mm astrograph at f/5 and the Canon EOS Ra at ISO 800 with LENR on as it was the warmest night of the summer, August 17, 2020. Aligned, stacked and mean combined in Photoshop. Autoguided with the ZWO ASIAir and ASI120MM guide camera with the RedCat on the Astro-Physics Mach1 mount. No filters employed here. Clouds thwarted more exposures.
