Comet C/2020 F3 NEOWISE: a new close-up 22 July 2020



Now that the comet is slightly higher above the horizon, I collected 39, 2-seconds exposures with the robotic unit. These frames were properly aligned, stacked and processed. The telescope tracked the fast apparent motion of the comet. At 19:17 UT the object was at a decent altitude (+25 deg.) above the NW horizon, at twilight.

The coma, which is the nebulous envelope around the bright nucleus shown is beautifully displayed. The sublimate gives the comet the "fuzzy" appearance that distinguishes it from the stars.

This closeup was possible by the Moravian G2-1600/KAF 1603ME camera setup with a pixel resolution 1.17" just over a 30x20 secs.
