Product Description

Orion Observer 80ST 80mm Equatorial Refractor Telescope
Orion Observer 80ST 80mm Equatorial Refractor Telescope
technical specifications for Orion Observer 80ST EQ  Telescope

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! Tracking celestial objects while viewing them in the Observer 80ST telescope is a cinch with the smooth and stable EQ-1B equatorial mount and tripod. The mount is equipped with dual slow motion controls for easy manual 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 with anti-reflection coating. This pint-sized refractor also includes the useful MoonMap 260 to help you identify interesting lunar features you can see in the telescope. A niftier grab-and-go scope you will not find!

Great beginners scope
5 Stars
Great beginners scope
Once you get the hang of it using the telescope becomes a breeze. You'll definitely need a 2x Barlow lens. Also chromatic aberration is an issue but that's expected from a small refractor. for my needs it's perfect.
