Vacuum

Low vacuum, also called rough vacuum or coarse vacuum, is vacuum that can be achieved or measured with rudimentary equipment such as a vacuum cleaner and a liquid column manometer. Medium vacuum is vacuum that can be achieved with a single pump, but the pressure is too low to measure with a liquid or mechanical manometer.

Can a Telescope Mirror be made of a reflective thin film?

A little vacuum pressure will make both surfaces concave spherical which can be used in a reflector T but to get a parabola is more difficult. At that level you can make a good mirror in half an hour if you have some aluminised mylar.
