These are a couple of the many pictures of Comet McNaught I took on January 11th from the roof of one of the buildings at work in Menlo Park, Ca. Exposure time was 1/30th or 1/60th of a second with an ordinary digital camera on a tripod. At the time, the comet was easily visible with a small pair of binoculars right after sunset, and was visible even naked eye, despite our urban location and marginal horizon. You can click on any image to get a higher resolution image.
|Unprocessed shot, which gives you an idea of what it looked like visually a few minutes after sunset. (Bring up the higher resolution version and look closely near the top middle. It's very faint.) Exposure was 1/60th of a second.|
|Same shot as above, except levels have been adjusted to show the comet better. I have not had time to do any serious digital processing - e.g. flat fielding to take out the vignetting, etc.|
|Another shot just before the comet went behind the trees. This was a 1/30th second exposure taken about fifteen minutes after sunset.|
