Comet C/2004 Q2 (Machholz), January 18th, 2005

A GIF animation of the comet's movement during 139 minutes. File size 2.4 MB, so it may take a while to load. See also a higher-resolution version of an indiviual image taken from this exposure series. The comet was moving fast, so stars are elongated even in individual 10- minute exposures. The autoguider was trained on the comet's core. The slight decrease in brightness of all objects within the image during the animation is due to the decreasing altitude of the comet during the exposure series, the background brightening was compensated for.

If the animation does not run smoothly in your web browser, you can save it to your harddisk and view it from there.
