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.

Reflectors     This is a reflector telescope. Reflectors (also known as Newtonian reflectors or catoptrics) capture light with a mirror at the bottom of a tube, which sends the image to the eyepiece at the top of the tube.    First-time telescope users sometimes have difficulty with the idea of looking through the side of a telescope, but the big draw for reflectors is that they are by far the cheapest to manufacture--and thus offer the best value--of all telescope types. They also generally have zero chromatic aberration.     Read more about different telescope designs in our buying guide

Some useful tech terms:

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.

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.

2.0 out of 5 stars don't like to complain but...., June 1, 2010

This review is from: Bushnell Deep Space 525x3" Reflector Telescope (Electronics)

My daughter's boyfriend gave me this telescope. Never owned a telescope, got it free, shouldn't complain...but this thing is not fun. The crude adjustments to the finderscope and main scope are very poor quality. And, as other reviewers have noted about other telescopes, the huge magnification makes no sense. I just hope this telescope will wet my appetite for something much better.
