My analog "storage" scope, which was old enough to vote in the last two
elections, was a "storage" scope because it came with a polaroid camera that
would mount to the screen, blocking out room light.  A little duct tape and
cardboard could make a hood that would mate your camera to your scope.  If
you can get it really dark in there, then open the camera shutter wide,
you'll catch anything that comes across the scope.  This might work best
with an old film camera with lots of manual settings.
