Tsuchinshan-ATLAS Comet

 


Comet C/2023 A3 (Tsuchinshan–ATLAS) is barely visible to the naked eye after sunset for the next week or two.  But point your cell phone camera to the west, and use "night" option. This graphic is from Sky & Telescope.



Some shots from last night across a soybean field looking west at 8 pm central time.

Details of photos are Samsung Camera, Model SM-G781U, F-Stop 1.8, 1/3 second, ISO-5000, Focal length 5 mm, Maximum aperture 1.69.  (this is for sixth picture, others are about the same).










That is a plane crossing the bottom of the last pic.
