Comet Lulin 31 Jan to 3 Feb

The image above shows comet Lulin in the morning sky from 31 Jan 09 to 3 Feb 09. (Click the image for a larger view.)
The widefield view was taken with a 28mm focal length lens. The mosiac of closeups on the right were taken with a 3" refractor, focal length 380 mm (~F5.2). The photos from 2 and 3 Feb were taken with ISO 800 and 45 sec exposure. The images from 31 Jan and 1 Feb were shorter exposures, so any impression that the comet has brightened in these photos is due to inconsistent exposure times.
