Comet C/2004 Q2 (Machholz), January 10th/11th, 2005

A GIF animation of the comet's movement during 104 minutes. File size 1.8 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. Background brightness changes are due to the decreasing altitude of the comet in the sky. All images were treated in the same way in Photoshop to get consistent results. Structural changes within the plasma tail can be spotted.

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