The difference between a telescope & telescope binoculars is one eye. And so… So far so good. With a telescope you peer through the lens with one eye & with telescope binoculars you use them both. Additionally, telescope binoculars are similar to traditional binoculars, only with a much longer focal length.

It has been said that an actual person can see more in the sky with a good pair of binoculars than with a cheap telescope, and telescope binoculars are designed with star gazing in mind with wider aperture opening to allow more light into the lenses, offering a brighter view of the viewing subject. There’re many binoculars on the market which can serve as telescope binoculars with the right focal length & magnification power, along with a reasonably wide lens opening.

Porro prism binoculars are better suited for night time gazing as they absorb less light through the prism path as do roof prism binoculars & will render a much brighter image when used as telescope binoculars in the typically low light conditions of nighttime viewing. However, upgrading optical quality & lens coatings are rapidly allowing the manufacturing of roof prism binoculars to meet the quality of porro prism units & they’re gaining in popularity despite the higher cost.

Mount Telescope Binoculars For Stability

When using traditional binoculars as telescope binoculars it’s best to have a unit with the capability to mount to a stable object such as a tripod or wooden deck to allow for better stability as well as in keeping them pointed in the same direction. Much like a telescope, they can be often used to spot smaller objects in the sky, but can rapidly lose sight of the object if moved & you’ll have to start the search all over again.

When searching for binoculars to double as telescope binoculars the numbers are important to know & understand. Binoculars are usually listed with two numbers, for example ten X 50. This would indicate a magnification factor of 10, meaning the object will appear to be ten times larger than the original & the diameter of the objective lens, in this case 50, determines the light gathering capability of the lens. Right. While an objective measure of thirty is good for daytime use, a fifty would provide typically good views at night.

To be effective as telescope binoculars, a magnification of 100 with an objective opening of seventy or more would be preferred. Remember that the longer the magnification & lens opening the more the unit is subject to shake when being held in the hands. A tripod or mount will reduce this & is virtually necessary with longer lenses.
