Comet NEOWISE at dawn

Comet C/2020 F3 NEOWISE from NW of Austin, Texas. Early morning clouds from Gulf moisture once again sent me NW of town to see this comet. It is a beautiful sight in 7x35 binoculars before dawn. This image was taken with a William Optics RedCat 250/51mm telescope and Sony a7iii camera. A Vixen Polarie star tracker kept the 15 second exposures sharp.

Exposed at f/4.9 for 15 sec at ISO 1600. Five images stacked in Nebulosity for a total exposure time of 75 sec. Exposure levels adjustment and crop in Photoshop with Topaz denoise.

This animation was made with a Sony a6300 and 50mm f/1.8 lens. Frames exposed for 8 sec, at f/3.5, and ISO 800. Sped up 60x at 1 minute / sec. From its appearance above the trees at the horizon to where it was lost in the glow of the approaching dawn was just over a half hour with only 5 to 10 minutes of prime viewing.
