Title

Telescope Celestron RASA 11" Cameras ZWO ASI6200MC Pro ZWO ASI6200MM Pro Mount 10Micron GM2000 HPS II Software Main Sequence Software Sequence Generator Pro (SGP) Pleiades Astrophoto PixInsight Description Project Notes: Always a novelty when a reasonably bright comet moves in position of a showcase DSO. But with 95% moonlight? With a backyard setup, I was able to block direct moonlight by hiding behind my house. Globular cluster Messier M30 appears lower right of the comet. Orbital Dust Trail continues to be despite the nearly full moon (in the comet's vicinity). Brownish-yellow dust tail appears as fan-shaped, 3 o'clock and above orbital tail as it was on July 27. Brightness measurement is mag 9.1 under heavy moonlight.
