 Comet C/2025 R2
            Swan (Northern Arizona) - 10/6/25

            
Oct. 6 at 7:30pm MST
            (Oct 7 @ 2:30 UT), RASA 8 f/2, RGB = 25 mins, ASI2600MC, N. of
            Payson AZ.

            
On the exact night of
            full moon, but of course opposite in the sky. Most light was
            from dusk anyway. The tail is a bit underwhelming at this point.
            A few sharp rays in tail here, and a lot of dust near the head.
            6000 feet elevation.
