Asking on wider range of newsgroups. Maybe others have already gone
down this road. Not sure if this will invoke derision from the CCD
folks.... :-)

One thing you might try is to remove the batteries and use the
external 120V power adapter. 4AAAs weigh 120 gm. Even if that leaves a
heavy camera, it'll lighten the requirement for the counterweights, if
you feel you still need those.
