Comet Holmes
This is a composite picture I took of Comet 17P/Holmes. The comet is the smudge right below the bright star near the middle. The stars near the middle are part of the constellation of Perseus, which extends off the shot to the right; the bright star near middle is Mirphak, and the bright star to its upper right is Algol (a variable star).
For the astronomers, it would appear that the limiting magnitude on this shot is around 6.75, (at least according to the magnitudes in Stellarium), which is certainly fainter than naked eye around these parts.
I took 32 5-second frames straight off my tripod, loaded them into Gimp, aligned and rotated each one, and merged the layers together. All told, I'm fairly pleased, although it was a bit labor intensive, (and rotating the images in Gimp was a bit more hit-and-miss than it could have been, as Gimp doesn't apply the layer transparency to the preview). So while I'm excited with the results, I'm not sure how often I'll go out and do this (although I will probably want to try Orion next, as winter approaches...)
