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.

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 anti-reflection coated 10mm and 25mm Kellner 1.25" telescope eyepieces. 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!
