Comet Pons Brooks
in the Evening sky
October 7, 2023 - 8pm

 
 This
            small comet is currently 11th magnitude, but will brighten considerably
            over the next four months. Close examination shows the peculiar
            dark notch in the inner coma, now highlighted by a bright internal
            rim that is horseshoe shaped. Very unusual appearance. This is
            an LRGB image - 15 mins of RGB binned 2x2 and 45 mins of Full
            size L data. 10" f/3.9, Atik 16200 CCD. Stay tuned on this
            one, it will just get better and better!
