Comet Lulin - 20 February 2009

This comet is currently moving rapidly through Virgo and into Leo. I had to take a series of short exposures, guided on a nearby star, and then combine them in Paint Shop Pro. As the comet moved from one frame to the next, the stars appear as trails broken up by the different frames.

Canon EOS 40D ,Canon EF 70-300mm f/4-5.6 IS USM
15 x 2 minute exposures at f5.6, ISO 1600. The lens was at full zoom (300mm) and piggybacked on a telescope for guiding. hide exif
