For beginning stargazers who want a starter telescope capable of providing more oomph, more performance than a traditional 60mm refractor, we present the Orion Observer 70mm Equatorial Refractor Telescope. Compared to a 60mm refractor, the Observer 70 EQ can reveal an even greater variety of stellar gems and provide greater resolution of old favorites like the Moon, Jupiter, Saturn, and the Orion Nebula. The Observer 70 Equatorial Refractor is easy for anyone in the family to operate, and its affordable price makes it a great telescope to start with as you discover the rewarding hobby of amateur astronomy. 

The Orion Observer 70 EQ Refractor Telescope features a multi-coated, achromatic glass objective lens that's 70mm in diameter, with a focal length of 700mm (f/10). This glass lens takes in 36% more light than a 60mm lens for brighter, clearer views. Bottom line: you'll see more than you would through telescope with a smaller aperture.

The refractor telescope optical tube is crafted from black-enameled aluminum and outfitted with a smooth-action, 1.25" rack-and-pinion focuser on one end and a dew cap/glare shield on the other. The telescope tube is held in quick-releasing tube rings on the Orion EQ-1 equatorial mount. Also made of aluminum, the EQ-1 mount supports the telescope and mimics the rotational axes of the Earth, which in turn allows you to manually "track" celestial objects with the Observer 70 refractor using slow-motion controls. For added convenience, an optional EQ-1M electronic drive (sold separately) can be installed to provide automatic, hands-free tracking.

The telescope tube and equatorial mount are supported on a sturdy aluminum tripod that adjusts to a comfortable height for virtually any observer. This telescope looks so good; you'll want to keep your Observer 70mm refractor on display when you're not using it!

The Observer 70mm Equatorial Refractor comes with everything you need to start observing right away, including a 90 star diagonal, EZ Finder II reflex sight, and 25mm and 10mm Explorer II telescope eyepieces. The 1.25" 25mm telescope eyepiece will provide 28x power magnification, while the 1.25" 10mm eyepiece boosts your views up to 70x power for closer looks.

This Observer 70mm Equatorial Refractor Telescope is a great choice for those just getting started in astronomy. It is lightweight and compact so it's easy to carry to your observing location, be it out on the lawn or an hour's drive into the hills. The telescope offers optical performance that will keep any observer entranced, evening after evening. Get in on the fun and get an Orion Observer 70mm Equatorial Refractor Telescope today!
