In the case of a binocular telescope, two is definitely better than one. That is not to say that the telescope has not be instrumental in advancing the field of astronomy, but binocular telescopes have added exponentially to this. Consider that the telescope can be traced back to the 1600s and it is obvious to see how far the device has come. By mounting twin telescopes, it gave a much better sharper magnification for the viewer.

Telescopes are measured and judged by the amount of light the primary lens is allowed to capture. By utilizing two identical optical systems, bound to the same axis much like binoculars, additional light is gathered, which produces impressive results.

For example, two 8.5 meter lenses will produce image quality equal to that of a 25 meter lens. The same results are true for smaller, hand held, telescopic compact binoculars and mounted versions. Additionally, focus is improved, as well as color perception, and eye strain is reduced by allowing the viewer to use both eyes, which is a more natural viewing position.

The binocular telescope has made its way from research installations into the hands of amateurs. Once used primarily in research installations, it is now being used by amateurs and novices world wide because of the advantages it has over other optical systems, such as monoculars and handheld binoculars.

Why is this? It is due to having a larger lens and focal length than their smaller handheld relatives. Add in the fact that they have a higher level of magnification and there is no comparison. The one drawback may be the fact that they are not as portable as their smaller handheld cousins, including compact binoculars and monoculars.

Such improvements come with a price. Standard monocular telescopes, with a 25 power magnification, sell for around $100. For the binocular version, expect to pay closer to $1000! And pricing goes up from there. While this may place them out of the reach of some amateur astronomers, the serious stargazers will no doubt relish the opportunity to utilize the improved lenses.

Don’t forget that many binocular accessories are available for the telescope versions. Exchangeable eyepieces for different magnification, adapters for frame or digital photography, and lens care products top the list. In this case, two lenses are definitely better than one. Have fun with your binocular telescope. There is just so much to see!
