Product Description

From the Manufacturer
Bushnell's NorthStar telescopes offer amateur astronomers state-of-the-art computer-driven location and tracking capability with simple, push-button control. With a built-in data base of 20,000 celestial objects, you simply call up your target on the hand-held control module, enter a simple "Go To" command and the NorthStar computer does the rest. Once locked on, tracking the object for prolonged viewing is automatic. Our innovative RVO (Real Voice Output) feature provides a fun, interactive way to explore the night sky. The remote, hand-held control module features red, backlit push buttons and a red, illuminated LCD read-out for easy viewing without impairing your night vision. The telescope also features our new 1x wide-angle, red dot finderscope. Additional features include a quick-release tripod and accessory tray for fast, easy assembly.

Tech Talk
Maksutov-Cassegrain: A design that utilizes a spherically curved front lens element in conjunction with a similarly curved primary mirror. This configuration provides incredibly sharp images in a compact folded-light path package. The total optical system provides a focal length much longer than the actual optical tube body length. GO TO Computerized Star Locator: This feature utilizes an on-board computer and advanced motorized technology to allow you to quickly locate and automatically follow over 20,000 pre-programmed astronomical objects with the touch of a button. Educational descriptions of each object are also provided. Barlow Lens: An auxiliary lens that increases the power by a factor. For example, a 2x Barlow doubles the magnification of the telescope.

4.0 out of 5 stars Satisfactory optics...completely lacking documentation..., March 20, 2007

By	Amerature Astonomer (Upstate New York) - See all my reviews

All in all a great backyard scope for those getting interested in Astronomy. The optics are good for planet viewing and star gazing. Deep sky objects will be faint so don't expect Hubble clarity. Moon gazing is unbeatable and Saturn is quite clear even without any filters. A good filter/lens kit really makes this scope go a long way. Once set up the "Go To" software works pretty good. Sometimes it says we are there and it requires a little hunting and pecking to find as it is just out of the field of view. For the money (Sam's club had these for as little as $200 on sale) this scope is a great starter. The cons are the complete lack of documentation included for set up and alignment procedures as well as total lack of any kind of support on Bushnell's web site. Even the astronomy links on the site are bad (as in do not work). Shame on you Bushnell for not properly supporting what is an otherwise very good product for the money. Value 10/10 Construction 10/10 Ease of use 7/10
Portability 10/10 Optics 9/10 Included accessories 6/10 Documentation 2/10
Website 0/10. Hope this helps. I really like it and would recommend it for the 200 - 300 price range but no more.

1.0 out of 5 stars Save up for a much better telescope, December 30, 2007

By	F. Campbell "Doc Morbius" (East Coast) - See all my reviews (REAL NAME)

This had the potential to be a nice way for my daughter and I to explore the night sky. But I cannot recommend this scope for several reasons. First, it is almost impossible to align the tracking scope with a centered object in the main scope making the next steps impossible. Second, the backlight LED display for the handheld computer is a very dark red and impossible to see - even in my very dark backyard. I fail to understand Bushnell's point in using a display you cannot see.

Save your pennies and purchase a wider aperature telescope if you really want to see celestial bodies.
