Comet NEOWISE Timelapse Video Captured by W. M. Keck Observatory Astronomer 

W. M. Keck Observatory Staff Astronomer Josh Walawender captured photos of Comet NEOWISE (C/2020 F3) during twilight on Friday, July 17 from Mauna Loa on Hawaii Island and created this incredible timelapse.
The video shows the comet setting, with Haleakala on Maui in the background and the west slope of Maunakea in the foreground.
These images/timelapse sequences were not taken with our Keck Observatory telescopes on Maunakea; Josh captured the comet from Mauna Loa using his personal camera.
