If you are a novice astronomer, and decided to buy a pair of binoculars for astronomical observations, this article is for you. Danny Meyer gathered all the information. We present three basic families of astronomical binoculars, which are the most popular and universal. These binoculars can be used without a tripod, and the choice of model depends on your preference, the manufacturer, the observation conditions (urban or field), as well as the type of the observed object in the sky. Binoculars 8 40 have a wide angle of view, the reason for their help easier to find objects to observe the Milky Way. Such a pair of binoculars would be a good complement to the telescope. The binoculars have a moderate size, and is well suited for family observation of children, its weight allows for a long time to observe objects without shaking hands. On luminosity and an increase in this family is in the middle between two others. These binoculars are not very demanding on the illumination and observer of the small diameter exit pupil (5 mm), but this diameter is not fully exploits the eye.
Less common are models of 8 8 56 and 60 with a diameter of about 7 mm pupil, it carries more weight than 8×40, and good conditions provide a better picture. Binoculars 8 8 30 and 35 are less popular, and generally considered to be poorer. For example, this model of binoculars: Carl Zeiss Conquest 8×40 BT *, Nikon Action 8×40 EX WP most popular family of binoculars has a 7 50. The larger exit pupil (7mm) uses the maximum possible wide-angle lens and the eye. But the picture quality is highly dependent on lighting conditions (illumination, twilight, midnight sun), and the age of the observer (in children more pupil in the dark than in adults). These binoculars are easy to observe with it, without installing it on a tripod, but with a small increase in the worse looking at the moon, double stars.
Wide field of knowledge and good luminosity make these Binoculars are very handy for finding a view of the sky, or nebulae, then you can use a telescope. Binoculars 7 30 and 7 35 easier, but they are worse in field observations (in the absence of city light). Examples of binoculars: Carl Zeiss 7h50 B / GA T * ClassiC, Binoculars Nikon Action 7×50 EX WP Binoculars 10×50 is the second type astrobinokley in popularity among astronomers. But these binoculars are the most difficult of the universal astronomical binoculars. They recommended a wide eyepiece, due to narrow field view. With such a binocular having a diameter of 5mm exit pupil can be seen more detail on the Moon, Jupiter, etc. Of course, its hard to compare with the telescope, but binoculars are also popular among astronomers.
