I did a bunch of searching and could'nt seem to find any answers.

Has anyone done some long exposures with the D200 and what +/- results did you get.

I just dont want to damage the chip

    How long you talking here? It has a bulb setting. I've only gone to under one minute.

    I did something like a 5 minute exposure with my D70, its got the CCd chip, not CMOS, but thats the best info i got for ya. I'm sure someone's done much longer exposures though.

    Well I was wondering about 5, 10, 15 min... how far can you go and if anyone has any experience they would like to share as far as what to avoid as far as noise and anything else they may have experienced.

    Long Exposure
    Using a big rubber band to hold the shutter button, I have shot star trails of one and two hours with my D200.

    Do make sure you have a fully charged battery in the camera before you start a multi-hour exposure, especially if the ambient temperature is cold.

    Some film cameras are still very viable for very long exposures.

    If you want to do very long exposures, to avoid excess noise, use long exposure noise reduction or manual dark frame subtraction methods. If you turn on the long exposure noise reduction remember that the camera makes a second exposure of the same duration as the image exposure to build the automatic dark frame.

    Understand that long exposures in digital cameras is rather hard on the electronic circuits as they are on for much longer than they were normally designed to be. Over a long period the accumulative affects can lead to "stuck" pixels and even camera failure.

    Some of the better grade cameras do have shutters with a latch so that at least the shutter is not energized during long exposures. This tends to save a lot on battery power as only the imager circuits are powered.
