Comet Holmes #2

Here's a picture, taken a few minutes ago. The first picture is straight from the camera. Comet Holmes is the fuzzy ball a little above center:

The following picture is the same as above except that I used PowerPoint to add a couple of arrows. The upper arrow points to Comet Holmes. The lower arrow points to the Pleiades.

Click on the pictures to enlarge them. The first picture is higher quality, and both Comet Holmes and the Pleiades are easily visible once you know where to look for them (after you click on the picture to enlarge it). The second picture shows you where to look, but the objects themselves are harder to see because the picture is lower quality.

Camera settings for my Canon A520: Put the lens on wide angle. (This is to obtain the maximum aperture. If you use the telephoto, it reduces the maximum aperture available.) Put the camera on manual, and set it for the maximum aperture (F2.6) and slowest shutter speed (15 seconds). Set the camera for the highest ISO speed available (ISO 400). Turn off the flash. And, of course, use a tripod.
