Comet C/2020 M3 (ATLAS) in Orion
There's a bright-ish comet passing through Orion these days [C/2020 M3 (ATLAS)]. It's the green fuzz at the top of the first photo, above Orion's three belt stars along with the decidedly bright Orion Nebula at lower right and nearby Horsehead and Flame nebulae around the. bottom belt star. The other image shows a detail of the comet with a longer focal length; no tail showing but a nice big coma. By the way the green is from carbon molecules excited by sunlight to emit mostly green light.
Nikon D800 (modified to record hydrogen light), 200-500mm f/2.8 @200mm, 20 exposures, each 90 sec., f/7.1, ISO 2500, iOptron CEM25P drive, processed in Lightroom, combined in Starry Sky Stacker.
