Observing the stars can be a scholarly challenge but still for children it is something a part of their enjoyment. Surely to visualize this enjoyable opportunity in an appreciable manner someone requires a telescope. But when it comes to telescope the number of participants viewing the stars becomes limited. Introduction of binoculars for astronomical viewing have produced appreciably good results, both in case of viewers number and their mobility. Though any kind of binoculars can be used for stars and sky view but still the efficient equipment promises superior results.
For amateur astronomers, astronomical binoculars can serve as the best and easiest way to learn their way around the dark night sky. While selecting astronomical binoculars technical and optical quality matters very much. Professional astronomers do it significantly because of their experience but amateur astronomers are mostly seen to embrace their romance of stargazing. Now why should some one prefer binoculars over telescopes for astronomical viewing? Answer can be very simple as the wonders of this universe can not be enjoyed through the single eyepiece of telescope. Binoculars provide almost three dimensional and comparatively wider views than the telescopes which enables more visualization at one time.
Magnification and aperture are the two basic parameters of binocular rating. In a (7 x 50) binocular, 50mm means the lenses diameter and 7 shows that the object is magnified seven times more than the original. The area of land or sky that is presented to your eyes is called field and surely the binoculars with larger field work significantly better. Through a telescope one can only view a part of large objects like 3.5° wide Andromeda Galaxy while through large aperture binoculars view of such objects fit in the field. With these astronomical night vision binoculars many nebulas objects like globular clusters, comets, and galaxies in their entirety can be visualized even in the star spangled deep darkness. Clarity is the other advantage of binoculars.
As compared to telescope, you see up to 40 percent more detailed object than normal. It is because your both eyes work simultaneously. In this way brain combines images from both eyes and instinctively uses the sharpest portion from both eyes to build a single and even sharper image. For binocular astronomy, water proofing is another important factor. Especially in damp or rainy conditions, binoculars with out the facility of water proofing can damage the optical coating. In this regard water proof Nikon binoculars can be an excellent option.
In the end, it is physically more comfortable to visualize through two eyes of binocular, rather than squinting through a single eyepiece of telescope. Studies have shown that the eye muscles are relaxed when both eyes open and viewer does not suffer eyestrain.
