I have been experimenting with digital SLRs in night photography. I have tried a Olympus E20N and the Pentax *istD, and concluded that each camera is very different. I finally figured out how to reduce the noise in the E20N for long exposures at higher sensitivities and using it's internal noise reduction features. I like the low noise, but due to the noise reduction technique it uses, it's harder to do streak photography. it takes several exposures and does averaging on them, which causes the streaks to have "jumps" in them. I'm still learning how to use my *istD in long expoure modes and have determined that it certainly is noisier than the E20N at the same sensitivity setting.
just want to see whether anyone has used these cameras and wants to share their experiences.

Re: DSLRs and night photography
Mon, September 3, 2007 - 10:57 PMlol... I know this is a couple of months late to your original post... But I've been testing almost every DSLR in every situation, and well... for long exposures, I recommend film. And if that doesn't help you at all... Well I think Nikon is releasing something new pretty soon... (maybe they already did.)

Re: DSLRs and night photography
Tue, September 4, 2007 - 6:37 PMI have the pentax k10d and I have found myself doing night photo's that I would have wasted half rolls of film just getting the exposure right, then the subject is gone. the K10D is much like the ist. I have found that I need manual exposure settings f stop and shutter speed. I have also found that a high iso and subtle over exposure. Depending on the situation I find that a streak effect is great when using a tripod and a remote so as to not touch the camera, touching camera causes a "jump" when working the bulb setting. however in "higher" light settings I have used no tripod and have been able to snap off a few shots so long as not to breath while the 3 second shutter speed does it's job.

Fri, November 27, 2009 - 4:00 PMI use a Canon 5D2 so I don't have much problem with noise.
When you use the noise reduction setting on a DSLR, it merely takes the same shot with the shutter closed and then subtracts the information from the original. You can do this yourself with photoshop or similar. Let's say you are out taking a dozen 20 second exposures, turn off the in camera noise reduction and just shoot for the same exposure time with the lens cap on. Then use the 'difference' blend in photoshop layers to reduce the noise in each of your pictures. This will reduce the jumps.
