Nice shot John, but as you know I'm fond of those long exposures ;)
If I get a chance to take some time off work tonight, I may give a 20 or 30 min exposure a try. I'm curious to see how much noise and how many hot pixels are produced. My only worry is that the camera might get too cold, you know, Minnesota and all. I suppose I could wrap it up in a blanket or something, just to keep the windchill off of it.

hey dude , thats an awesome picture, i love long exposures!
i think that they are really cool, i wanted to try to do some action ones sometime, like with a tennis player or something...?
I've never managed to get a really long exposure without things like the road becoming more exposed than I would have liked. I may have been trying in areas with too much ambient light maybe.
There may be a few hot pixels in this one but i'm not sure if it's that or if they are lights in the distance. At any rate, they can be cloned out if necessary :)

Here's a 4-minute exposure from back in August. Taken well after sunset, it was really quite dark, with just a hint of light in the west. the streak is an aircraft.
Taken with a Tamron 19-35mm lens @ 19mm, F5.6, ISO 100.
No noise reduction or dark subtraction. there are some hot pixels creeping in, but they don't show too much on the 640 version.
This is a 7 minute exposure. I want to go back to this spot a little earlier so I can catch a bit of color in the sky. This is facing due west...
This is really nice, I like it. You should try a 15 or 30 min in the same spot with the same conditions if you want color in the sky.
I miss having long exposure capability with my G5, the longest I can get is 30sec.
I made a 3 hour exposure in a garage with my 4x5 once. After some special film developing techniques, I was able to make a straight B&W print that had detail inside a cylinder of an engine block in a dark corner and the writing on the flourescent tube was readable. Thing had detail over something like a 15 stop range. Of course, digital cameras don't have reciprocity failure like film does.
I suppose this would be a good thread to again mention this (almost) 9 minute exposure I made last spring. I was suprised how long the star trails were in this shot...ah yes and the wind generators in the image happened to be off at the time. ;)
Yes, there is some noise in the dark parts of the sky (visible on the full res version), but for the most part it's a fairly clean image. I suppose should really try to use neat image on it.
Biggest problem I found with long exposures with my D60 was the battery heat showing up after about 5 minutes. I'd been shooting for about an hour fairly continuously by that point though.
Since my camera is limited to a maximum exposure of 30s and I know other cameras have similar limitations, I was wondering if anyone has tried "stacking" multiple exposures of 30 sec or less to effectively achieve long exposures. I think I'm going to try one or two this weekend.
One question from me ... what do you people do while you wait for the picture to finish? Do you read? :)
I'm usually by myself when I shoot these. I just enjoy the silence and solitude of the night. Reading requires a light and at long exposures like this, even the light from a small reading lamp could impact the resulting image.
