Embark on a fascinating adventure through our solar system and beyond with National Geographics StarApp 70mm telescope. This refractor is great for lunar, planetary and deep sky observing and has a special mount that allows users to attach their smart phone to the telescope and use the ARTelescope App to locate and learn about constellations and planets. As observers move the telescope across the night sky, they will hear facts about the constellations and planets in the apps database as they come into view. The telescope comes with two interchangeable eyepieces and a 2x Barlow lens to provide a versatile range of magnifications.
