    Orion 70mm Observer Altazimuth Refractor Telescope

    The Orion Observer 70mm Altazimuth Refractor Telescope is well suited to beginners of any age. 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. 

    Its glossy black optical tube is made of seamless aluminum and outfitted with a smooth-action rack-and-pinion focuser on one end and a dew cap/glare shield on the other. Housed inside is a multi-coated, achromatic glass objective lens that's 70mm in diameter, with a focal length of 700mm (f/10). This lens takes in 36% more light than a 60mm lens. Bottom line: you'll see more. So, if you can afford the modest additional cost of an Observer 70mm over a 60mm refractor, it will reward you with brighter images and, for astronomy, a larger repertoire of objects to see. You'll enjoy outstanding looks at the Moon's cratered surface, Jupiter's cloud bands and moons, Saturn and its rings, the majestic Orion Nebula, and the mind-boggling Andromeda Galaxy, to name just a few of the treasures you can see. 

    Orion specially engineered the altazimuth mount to provide much greater stability than the standard "off the shelf" altazimuth mounts. It has an altitude micro-motion control to allow very fine aiming adjustments. The tube and mount are supported on a sturdy aluminum tripod that adjusts to a comfortable height. It looks so good, you'll want to keep your Observer 70mm on display when you're not using it.
