What was the shutter speed?

It looks like a long exposure photo that was nocked half way through.
Thats what it looks like to me anyway.

Looks like it could be a reflection on the lens. I have had a couple of shots like this in the past.

Denial I think you are right this was taken when trying to image comet P/Holmes so the exposure was about 2 sec.

My guess is you've bumped the shutter button when moving the camera. You say the shutter speed was about 2 sec... It looks like you've opened the shutter just as you're about the move the camera, hence the faint image of the front of the shed, then as your moved the camera to the right the light has come into the FOV from the right.

I'd say its one exposure but your subject matter has changed with 2 periods of relative stability at the start and end of the exposure.

Yeah i agree with Sheeny, i have actually done exposures where i have had a friend of mine staring up at the stars while keeping the shutter open, i used a flash to illuminate the foreground and friend and kept the shutter open long enough to get good star trails, the result looked like a ghost looking up at the stars!

Phil it's a single exposure and the EXIF info on this shot is:
Canon 30D
400 ISO
f/4.5
6 sec exp
30mm FL.

Had a closer look and I'd agree with Al and Daniel.
At first I thought you may have changed zoom ranges on the lens but Al is right, it looks like you've moved the camera.

Yeah, a bit more practice and you'll be able to make that light look like a comet...
