I'm unable to see images, so I can't identify the type of telescope shown. However, common types of telescopes include refractors, which use lenses to focus light, and reflectors, which use mirrors. If you provide a description or specific features of the telescope, I can help determine its type.

Yes, a Hershelian telescope is a type of reflecting telescope in which the primary mirror is tilted so the observer's head does not block the incoming light.
The Chandra telescope was built to observe X-rays.
