Default Telescope

Received this as a gift, but never got to use it. I'd rather see it go to a good home than collect dust. It lists for over $300 and sells for $240 on Amazon - just make me a reasonable offer!

The following is a description from Amazon:



From the Manufacturer
A quantum leap for computerized telescopes, the North Star offers novice telescope users a plethora of celestial views at the touch of a button. Advanced motorized "go to" technology enables the computer to automatically find and follow any object from its 20,000 object database. Includes a remote control handset with red illuminated LCD readout and red backlit buttons. Also features the new wide-field red dot finderscope, which utilizes a red LED projection. This 1x finderscope will easily allow any user to quickly sight in an area of the sky and find night sky objects quickly. Additional features include quick release accessory tray and tripod legs for an easy two-step assembly.

Specifications for this Bushnell telescope include:

* Power/Obj.: 525x3"
* Style: Reflector
* Focal length: 700mm
* Features: 20,000 Object Onboard Starfinding Computer With Real Voice Output, Kinematic Motion, Quick-Release Adjustable Aluminum Tripod, 1.25" Format Eyepieces, Barlow Lens, Red Dot LED Finderscope, Accessory Tray, Camera Adaptable, 2-Step Assembly


Tech Talk
Magnification (Power): The magnification of a telescope is determined by dividing its focal length by the focal length of the eyepiece being used. For example, a 500mm telescope with a 5mm eyepiece would magnify objects 100x. Thus, a telescope can provide nearly any magnification required depending on the focal length of the eyepiece used.

Objective Lens Size (or Aperture): The size of the telescope’s objective lens, or aperture, limits the amount of power that can be used effectively. As the magnification of an object increases, the brightness of the image decreases. This is because the light gathered by the telescope is being spread over a larger area.

Reflector: The optical system in a reflector uses a primary mirror to reflect the light from a distant object such that it can be focused to a point and magnified by an eyepiece. Popularized by Sir Isaac Newton in the 17th Century, it is sometimes referred to as a Newtonian reflector.

Focal Length: The measured light path of the optical system (tube length), typically measured in millimeters.

"Go To" Computerized Star Locator: Utilizes an on-board computer to find over 20,000 astronomical objects. Educational descriptions of the objects are provided at the touch of a button. Plus "go to" advanced motorized technology, where the computer automatically finds and follows any object from its 20,000 object database.

Product Description
See amazing sights in the starry night with the Bushnell Northstar! This impressive telescope pairs amazingly advanced features - computer-driven location and tracking ability, the "go to" feature. Real Voice Output, and Red Dot finderscope with a simple, push button control. Amateur astronomers appreciate a programmed database of 20,000 celestial objects making the cosmos within reach. When using the 20mm lens, magnification is 35x; using the 4mm lens, magnification is 175x. Adult supervision recommended. Measures 44"L x 4"W x 48"H.
