Astrophoto: Comet Garradd by Bob Christmas

Comet Garradd (C/2009 P1) is currently the most visible comet in the night sky. This makes it one of the most favorite targets for binoculars and small telescopes. As this comet remains visible in the coming months, we surely won’t be missing the sight of this very soon.

This is an image of Comet Garradd (C/2009 P1) taken by Bob Christmas from near Barry’s Bay, Ontario, Canada on the evening of September 25, 2011. “The comet was in southeastern Hercules. North is to the right in the image.”

This image is a stack of 8 images of just over 2 minutes exposure each, for a total exposure of 16 minutes 41 seconds. Bob used a Canon Digital Rebel 300D camera and a Tamron 300mm f/2.8 telephoto lens, mounted on an unguided Super Polaris EQ mount. His setting are f/2.8 and ISO 800. Stacked using Deep Sky Stacker and post-processed using The Gimp.
