    It is possible to overheat your camera by taking too many consecutive frames or had a series of consecutive long exposures?

    I'm sure it's possible, but I doubt you'll ever do it. I think you would be more likely to do damage with one very long exposure.

    Yes. While picking up a lens from a repair shop I saw a 300D with a dead sensor due to what was apparently only a single sub 30min exposure. I have taken a 45min exposure with me D200 without damage but the outside of the camera was hot to the touch. I would hate to think how warm the sensor itself got.

    Never doing that again.

    Like Garbs said yes. When I used to have my cookbook CCD camera for astrophotography, I used to cool it with nitrogen. Otherwise it would have only lasted for a couple of shots.

    thanks guys, yeah I was taking a bunch long exposure yesterday and then I was like "hmm, wonder if this is such a good idea?" The exposure only lasted 15-20 seconds a piece and I took like 15-20 shots so I guess no big deal at all.

    Hmm, it is surprising that they never have put a sensor.

    I would imagine it's something that affects point-n-shoots more than DSLRs. For example, I was checking out a Fuji S9100 and in the manual it even stated you could overheat it, so give it a break once in a while from "hi performance" mode. DSLRs should be build more rugged with rapid fire in mind.

    Series of short exposures are no problem. Dslrs slow down after so many anyhow because they need to clear the buffer. But the sensors dont get hot from that.

    It shouldnt cause a problem. It may also depend on how fast you are shooting those 15-20 shots. If the intervals one right after another of the same subject you might warm it a tad.

    If you're trying to overheat the sensor at 5 frames per second you're more likely to screw you shutter than you are overheat your camera.

    You could get a mechanical film camera for long exposures. No worry about overheating or batteries dying.

    Or noise! Without specialised gear (I am talking about digital cameras with heat control on their sensors, and 1mpx sensors with huge photosites) film completely annihilates digital for cheap hobby astrophotography.
