Yes, it is standard policy to super-cool photographic, as well as
electronic, cameras for astronomical use.  Films are normally gas-hypered,
then a cool-box camera is used.  See, for examples, the LUMICON ads in
every issue of Sky & Telescope.

The increased sensitivity is to visible light, not cosmic rays, which are
what fog films over a period of decades.
