Unveil Dozens of Cosmic Treasures Tonight!

   
  • A great telescope for beginners interested in nighttime stargazing and daytime terrestrial viewing
  • 70mm aperture and 700mm focal length for wonderful views of the moon, planets,     nebulas and galaxies
  • Includes a sturdy tripod and an altazimuth mount for simple horizontal and vertical     movement
  • Includes two eyepieces, finder scope, focuser, diagonal, and FREE Starry Night astronomy software
Telescopes needn't be exclusively nighttime creatures. By virtue of its altazimuth mount, this one works well for both daytime terrestrial viewing and nighttime astronomical use. The altazimuth mount offers intuitive up-down, left-right motion to make maneuvering the telescope easy. Whether for panning a scenic landscape or surveying the Milky Way for star clusters, this scope provides a pleasant experience.

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 70 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.
The Observer 70 Altaz comes with everything you need to start observing right away. Standard accessories include a 5x crosshair finder scope, mirror star diagonal, 10mm (70x) and 25mm (28x) Explorer II eyepieces, and a tripod accessory tray.
It's a telescope that will keep any observer entranced for years. Get in on the fun, get an Observer 70!
