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 Orion Observer 70mm Altazimuth Refractor Telescope 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 telescope provides a pleasant experience. The 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. We 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.

The Observer 70mm telescope comes with everything you need to start observing right away. Standard accessories include a 5x crosshair finder telescope, mirror star diagonal, 10mm (70x) and 25mm (28x) Explorer II telescope 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 Orion Observer 70mm Altazimuth Refractor Telescope today!

Point yourself, and your telescope, in the right direction with the included Orion SkyLine Kit. Featuring the Orion SkyLine Deluxe Green Laser Pointer, Orion Shorty 2x Barlow Lens, and Orion Beginning Stargazers Toolkit, the Add SkyLine Kit enhances your ability to sight objects in the night sky, magnify your view of such objects, and to learn about them and when they can be viewed.

The Orion SkyLine Deluxe Green Laser Pointer is a perfect tool for stargazers. It emits a thin but distinct green laser beam that appears to stretch all the way to the stars! The SkyLine provides a wonderfully interactive and fun way to identify tars, outline constellations, and decide where to aim your telescope. It even works in light-polluted or moonlit skies! It's great for pointing out stars, planets, and more for others to see. The SkyLine Deluxe uses electronic feedback regulation to ensure ultra-stable beam intensity compared to other green lasers on the market, even in cold temperatures. The aluminum body is 6" long and features a pocket clip. AAA batteries are included for operation.

A 2-power (2x) Barlow lens is an extremely versatile eyepiece accessory that doubles the magnification of any eyepiece installed. For example, when using the Observer 70 AZ with its 700mm focal length, using a 10mm eyepiece will yield a view with 70-power magnification (700 divided by 10). If you installed the same 10mm eyepiece into the Shorty 2x Barlow Lens and then inserted into the Observer 70mm AZ telescope, your viewing magnification would be increased to 140-power magnification (70 x 2). Barlows are great accessories for any amateur astronomer, since they allow you to double the power of the eyepieces included with your telescope. They're a great and affordable way to add to your arsenal of viewing magnifications. What's more, the Orion Shorty 2x Barlow gets its "Shorty" moniker from its compact size compared to other Barlow lenses, so it's easier to find a spot for it when packing your gear for a night under the stars.

With the included Orion Beginning Stargazer's Toolkit, you'll never be "lost in space!" It contains four items designed to help new astronomers find their way around the heavens.

  1. Star Target Planisphere - Dial in your local date and time and it shows you the locations of the constellations and deep-sky objects in the night sky
  2. Discover the Stars - A wonderfully written and illustrated observer's guide
  3. Moon Map - Identify craters and other lunar features with your telescope
  4. Orion RedBeam Mini LED Astro Flashlight - Emits pure red light that won't spoil your night vision. Perfect for reading your planisphere or seeing what you're doing at the telescope
