Here's a pair of telescopes on a stand where a more experienced astronomer can look up and show another person the sky and objects.

This has a refractor and small reflector designed as a comet catching telescope. What is a comet catcher? It's a wide field scope a visual astronomer might use ti search for comets. Usually f5 or f4. Something with a short focal length.

Of course comet catching telescopes that are used by astronomers are usually fairly big. In the past some comet hunters used large binoculars as well.
