What makes a telescope expensive is the perfection of the shape of its mirrors and lenses, the quality of the glass, the stability of its mounting and how smoothly the mounting moves as the telescope points to different parts of the sky. It is a precision mechanical device that does not make use of any special gas.

Hi. In the case of one of the MOST expensive there is no gas at all. The Hubble is open to space vacuum.

There really is no reason to use any particular gas as long as it is as free from moisture as possible. The moisture could condense on things in cold temperature, and instigate corrosion.

They usually use nitrogen
Our air is 80% nitrogen, so you can find it everywhere
