Jupiter and Saturn nearing their December 21, 2020 Great Conjunction, with this image taken December 14, 2020 from home in southern Alberta. This is a panorama stitch of two images, each a blend of 4 untracked images for the dark ground and stacked to smooth noise, plus a stack of 4 tracked images for the sky, all with the 85mm Rokinon lens at f/3.5 and Canon EOS Ra at ISO 400. The camera was on the Star Adventurer 2i tracker, only roughly polar aligned as Polaris was not readily visible amid clouds to the north and in the bright sky. Diffraction spikes added in Astronomy Tools actions. Stitched in Photoshop with Photomerge. Taken well past traditional "blue hour" but when there was still a lot of colour in the sky to the camera, yet the sky was dark enough to show other stars.
