A clear night is hard to resist, and I wanted to try out another lens. Comet C/2023 A3 is no longer visible to the unaided eye, and in fact it took some effort to find with binoculars. It is no longer the spectacle it was less than a week ago. The sky brightness was sqml=21.0 at the time of this image. Camera: Olympus E-M1iii + Olympus 50mm f/2 ED macro lens.

In addition to the comet, there are a lot of other interesting objects in this field of view. The same image is presented below with some labels added.
The three circled star clusters range from about 1200 to 1600 light years distant.
To the right of the comet is Barnard's Star. At a distance of just 6 light years, this star is the second closest to our sun after the three-star Alpha Centauri system. It is a red-dwarf star with an estimated lifetime of over a trillion years.
Here are a couple cropped views:
