The difference between a telescope and telescope binoculars is one eye. With a telescope you peer through the lens with one eye and 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 a 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 are many binoculars on the market which can serve as telescope binoculars with the right focal length and 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 and will render a much brighter image when used as telescope binoculars in the typically low light conditions of nighttime viewing. However, upgrading optical quality and lens coatings are rapidly allowing the manufacturing of roof prism binoculars to meet the quality of porro prism units and they are gaining in popularity despite […]

When viewing distant objects through the use of a telescope, the most important part of that telescope is called the objective. The objective is that component of the telescope that has the ability of gathering the light that is available. Obviously, the larger the objective the greater is the capacity of the telescope to gather light which in turn allows the viewed image to be better visualized.
In addition, there are two types of telescopes. One type of telescope is called the refractor telescope and the other is known as the reflecting telescope. The difference between these two telescopes is how the light is captured.
Refracting and Reflecting Telescope
The refracting telescope obtains the light through its objective that is made out of glass. Basically, in this type of telescope, the glass lens is situated towards the front of the telescope. As the light is captured by the objective, it is then refracted or deflected through a lens which allows for the viewed image to be magnified. Examples of this type of telescopic equipment include scopes that are used on rifles, binoculars and spyglasses.
A reflecting telescope uses a mirror as its objective. This mirror is located towards the distal end of the telescope. […]
