Mercury and Comet C/2002 F1 (Utsunomiya)

By coincidence Comet Utsunomiya passed very close to Mercury during this period of alignment of the planets. Unfortunately it is so dim, small, and buried in sunset glow that it is not visible in the wide angle shots. This photo was taken using a 4" Borg refractor approximately 1 day after the comet's closest separation from Mercury. Technical data:
