With all-metal optical tube assembly, high-quality glass optic objectives for crisp clear views, full-length variable height tripods, metal yoke mounting systems, all-metal accessory trays, rack and pinion focusing mechanisms and patented universal coding system, they can help you take a voyage to hundreds of far-away galaxies, learn about the moons of Jupiter, and explore the craters of the Moon. Meticulously engineered, the advanced optics of Bushnell Telescopes deliver amazing detail and will keep viewers enjoying the wonders of the universe for many years to come.
Specifications for this Bushnell telescope include:
| This is a refractor telescope. Refractors (also known as a dioptrics) capture light with a lens at the front of a long tube and send it to an eyepiece at the other end. They look, in other words, just like what most people think of when they hear the word "telescope." |
Refractors offer--potentially, at least--the cleanest images of any telescope design. They are simple and reliable (the sealed tube is maintenance-free), and are good for both celestial and terrestrial viewing.

Some useful tech terms
- Power/Obj.: 420 x 60mm
- Style: Refractor
- Focal length: 700mm
- Mount: Yoke
- Key Features: Land Eyepiece
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 telescopes 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.
Focal Length: The measured light path of the optical system (tube length), typically measured in millimeters.
Yoke Mount: A u-shaped altaz mount. Altaz mounts move up-down and left-right.
Finderscope: On most astronomical telescopes a lower powered finderscope with a wider field of view lets the user quickly locate the object to be viewed by the high-magnification main telescope.
