Can you see Cygnus Centauri and Virgo with an ordinary telescope?

Look at the constellation, you don't need a telescope to see it, you look at it with the naked eye.

A constellation is an area in the sky. Find some representative stars in it and connect them with imaginary lines to form a constellation.

The longer the focal length of the telescope, the narrower the field of vision, and it is difficult to see the whole picture with the telescope.

Telescopes are used to observe specific stars or nebulae.
