ISEN-ASTC-L is a service of the Association of Science-Technology Centers
Incorporated, a worldwide network of science museums and related institutions.

That sort of thing works better with cheaper cameras. Try one of the < $50 board cameras from Supercircuits or Spytown.
Another thing:
Outfits like Thor Labs and Melles Griot have modular optical mounts that accept standard microscope objectives (DIN or RMS thread) and
c-mount devices either internal or external thread. So for not too much you can make a very nice "laboratory style" video scope.
