Ideal for beginners or intermediates, the Inspire 100AZ 100mm f/6.6 Alt-Az Refractor Telescope from Celestron has the largest aperture and shortest focal length in the Inspire series, which makes it as powerful as it is compact. The combination of aperture and focal length translates to a fast focal ratio, and therefore allowing for short exposure times when performing astrophotography using the included smartphone digiscoping adapter. It is intended to give novice astronomers a complete rig that is easy to set up and use for making detailed observations of the Moon; and viewing the planets, meteor showers, and brighter deep-sky objects with the resolution to split binary stars and separate clusters.
