Description

Comet NEOWISE setting over the Colorado Rocky Mountains July 15, 2020. The red and green banded airglow is from oxygen emission above 90 kilometers in our atmosphere. Comet NEOWISE displayed a yellow dust tail about 16 degrees long which was an impressive sight both with unaided eye and in binoculars. The blue ion tail stretches about 25 degrees in this image, and the brighter portion could be seen in binoculars.

35 mm f/1.4 at f/1.4, iso 1600 14 seconds on sky, 22 exposures, tracked with an iOptron skytracker, 90 seconds on land, no tracking, 3 exposures.
