Description

The January 2019 Total Lunar Eclipse taken from Arlington, TX. This image is a composite of processing the data twice, once focusing on the background sky, and once focusing on the moon details. There were thin clouds on and off throughout the night, which may have led to the radiant glow around the moon.
