Ritchey–Chrétien under the Milky Way at White Mound.webm

A 20 cm (8 inch) Ritchey–Chrétien telescope images under the dark skies of White Mount County Park, Sauk County, WI. The telescope, mount, and other equipment are marked with glow-in-the-dark tape, which was initially charge with a UV light, and can be seen fading rapidly as the video begins. The telescope initially collected luminance data on NGC 5434 and surrounding galaxies, then was directed over to the Eagle Nebula to gather a small amount of near infrared data as astronomical dark ended. The end of astronomical dark can be seen in the last few seconds of the time-lapse. Many satellites can be seen in the night sky, moving at different speeds. There are also some unusual flashes of light, mostly visible on the right half of the frame above the tree, which I cannot explain (but one suggestion that seems sensible is that they're flaring satellites in similar orbits).
