I tried to photograph the comet Loneos (C/2007 F1) just after sunset. A cloud that made a beautiful sunset just sat there slowly creeping up toward Arcturus. As often seems to happen, Pittsburgh weather got in the way of my astronomical viewing. This time, though, the weather provided something interesting to watch in its own right. You can click on these small versions of these time-lapse photographs to see the VERY LARGE versions:
The lowest star you can see near the sunset is Arcturus. The comet was one degree below that star, but was never visible, even with a 30 sec. exposure. The cloud obscured too much.
The Big Dipper is an "asterism," not a constellation' it's part of the Great Bear (Ursa Major) constellation. This photograph makes it easy to see.
As you can tell, I'm still having fun with the camera.
