Description

From my backyard, using my telescope and camera, I captured the motion of Comet 21P/Giacobini-Zinner over an 18 minute period. The 18 minute movie was later compressed into a handful of seconds to better highlight the comet’s motion. The "movie" consists of 6 images, each 3 minutes in duration consolidated in an a single animated GIF file. The movie was cropped to exactly cover a one square degree swath of sky (about twice the apparent size of the moon). The line that appears at around the midpoint of the movie is a satellite or much less likely a shooting star (meteor) that streaked by.
