Comet Lemmon
Comet 2025 A6 Lemmon over Tucson from Tanque Verde. I didn't expect to be able to image this from Tucson, but here it is in a shot that cuts through the city's light dome from east to west.
WO RedCat 250/51mm, Baader Skyglow Filer, ASI2600 MC camera, ASIAIR Plus controller, AM5N mount. Processed in PixInsight and Affinity Photo. #astrophotography
