Celestron ExploraScope 70AZ f/10 Doublet Refracting Telescope

The ExploraScope 70 AZ from Celestron is an excellent 70 mm (2.76-inch) Achromatic Refracting Telescope for anyone interested in celestial targets like the rings of Saturn or Jupiter's Red Spot. From the former planet of Pluto to our own Moon, and to any object within our Solar System, they can all be valid targets for the ExploraScope 70 AZ. It provides splendid clarity and superb quality of views and images for your enjoyment and is an all-around great value observational telescope.

The ExploraScope 70 AZ comes with a pair of eyepieces of different focal lengths and magnifications as well as a 3x magnification Barlow lens to help you widen your choices of further away observable objects. The StarPointer finderscope will help you find your targets and the 90-degree erect image star diagonal lets you see those targets in a top-side-up view. These all add to further enhance your observation experiences. Those are accompanied by an Alt-Azimuth Mount, an aluminum-tube leg tripod with accessory tray/spreader for stability to hold and help you aim your telescope to the objects of your choice.
