Comet Holmes - 29 October 2007

This strange comet was visible only in very large telescopes until it suddenly brightened by nearly a million times last week! It is now visible, in the constellation Perseus, to the naked eye. Binoculars or a telescope will reveal the disk-like appearance of its dust & gas cloud or 'coma'. Compared to yesterday's photo, the increase in size of the coma is obvious.

Camera 'piggybacked' on a Celestron C8 telescope. 84 second exposure at f11, ISO 400. I have cropped the original photo heavily. full exif
