Comet NEOWISE Close-Up (July 10, 2020)
A telescopic close-up of Comet NEOWISE (C/2020 F3) on the morning of July 10, 2020 with it in blue dawn twilight. The yellowish dust tail is promiment but a fine blue gas tail is just barely visible. Clouds prevented shooting earlier when it would have been in a darker sky and even so I was shooting through breaks in the scattered clouds.
This is a median combine stack of 6 x 45-second tracked but unguided exposures with the SharpStar 76mm apo refractor at f/4.5 for 340mm focal length and the Canon EOS Ra at ISO 800.
