    35mm cameras and DSLRs are heavy. Significantly heavier than, for instance,
    Coolpix or Powershot cameras. Hence I would not recommend mounting them on a
    scope without a dedicated photoport. I also would only use an external
    shutter with this type of camera for photomicrography. Even the slightest
    vibrations can quickly ruin the picture. Nachtigall talks about this problem
    on page 62ff in his excellent book. He recommends very short exposures
    (faster than 1/100 second) or very long exposures (more than 2 seconds) to
    avoid vibrations due to mirror slap and shutter curtain. Or get an old
    Olympus OM 2. With DSLR and static subjects, "bulb mode" (with manual mode)
    is recommended.
