Comet 220P McNaught in the Morning sky
in Cetus
8/26/26

 

            
 Last chance
            this morning before the full moon washes out sky. Was able to
            squeeze in 1h 15m of integration in a moonless dark sky this
            morning. Field here is about 2.5 degrees wide, and comets tail
            is easily 2 degrees in length. G2V calibration for most accurate
            colors of stars and comet.

            Notice the rich galaxy cluster up in the upper left corner!
