This complete telescope and accessory kit is a must-have for backyard astronomers who want to start exploring the wonders of the night sky. This short focal length refractor telescope gives wonderfully wide views of the night sky. You do not need a big, bulky telescope to enjoy backyard astronomy. Our potent little Orion Observer 80ST Equatorial Refractor Telescope proves otherwise. Compact and hassle free, it's easy to take outside and set up, and easy to bring in when you're done. This versatile telescope's 80mm-aperture objective lens has a short focal length of 400mm (f/5), which makes the Observer 80ST extremely portable and compact. Thanks to the telescope's fast f/5 focal ratio, bright, wide-field views of the stars and deep-space objects are the Observer 80ST's forte! The included EQ-1B mount is equipped with dual slow-motion controls for easy tracking of objects in the night sky. The Observer 80ST refractor telescope comes with a reflex sight, 90-degree diagonal (1.25"), and 10mm and 25mm Kellner 1.25" telescope eyepieces. The Orion Observer 80ST Equatorial Refractor Telescope is better than ever when used with the extra accessories in this value-packed kit. Use the Shorty 2x Barlow with the 25mm eyepiece that comes with the telescope to enjoy 32x magnification compared to 16x, and the combination of the 10mm eyepiece and Barlow bumps the magnification from 40x to a powerful 80x view for closer looks. Use the included MoonMap 260 to properly identify lunar features you see through the telescope. Read the included Orion Telescope Observer's Guide book to learn how to locate and observe over sixty interesting objects to explore in the telescope. Use the Star Target Planisphere to see what constellations and objects will be visible on any day of the year. The RedBeam Mini flashlight makes it easy to refer to charts and books while observing, and it helps you see small parts and knobs without disrupting dark-adapted vision.
