The Hubble Space Telescope is a reflector, so its objective is not a big-moose lens at the front;it's a big mirror in the back.The diameter of the objective mirror is 2.4 meters(7.87 feet), (94.5 inches).
The primary mirror of the HST has a diameter of 2.4 m; the secondary mirror measures 30 cm in diameter.
As big an error as it was for imaging, the actual flaw was only about the thickness of a human hair.
HST's primary mirror is 3 meters, or 118.110 inches.

I am assuming you meant, "mirror". in that case, yes. A teloscope uses a mirror.

the mirror was not right
The secondary mirror of the Hubble Space Telescope is positioned in front of the primary mirror, mounted on a support structure called the "spider." It reflects light collected by the primary mirror towards the telescope's instruments. This configuration allows Hubble to focus and capture detailed images of astronomical objects. The secondary mirror's placement is crucial for the telescope's overall optical performance.

when was the first teloscope made?
No, it isn't. The Hubble Space Telescope is a reflector. It has a primary mirror, and not a primary lens.
HST's primary mirror is a Cassegrain Reflector.
The Hubble telescope was a basic reflector telescope with a 94.5 ft mirror. The Hubble collects light though its open end, the primary mirror reflects the light to a secondary mirror that then reflects the light through a hole in the primary mirror to a focal point of the instruments or eyes of the Hubble.
The Hubble Space Telescope is not as big as the moon. It is as big as the space shuttle cargo bay.
