    Much appreciated, Bill.
    The great work on this thread has me considering a converted digital camera, but I don't think anyone converts digital cameras to higher than 850nm.

    It probably depends on the camera, but at least for my Olympus conversion was easy. Remove a couple screws and connectors to reach the sensor, then lift off the glass filter atop it. After that you can use it as a full spectrum camera, allowing for EIR type images like the one attached, or screw on an IR filter of any wavelength.

    Well done, Matt. A bird in flight isn't something I couldn't get with just a filter on the lens. How hard was it to modify your D70?

    Thanks Peter!
    The D70 wasn't very hard to modify. There were a couple of thin-film ribbon cables that were a bit tricky to re-seat properly. But even with a couple of reassembles to get said ribbon cable correct, it didn't take more than an hour.

    Interesting photos, Peter. How was you camera modified for IR?
