Sea Tips: Due to the lower magnification binoculars when focusing and observation are not allowed, air jitter and other reasons, limiting magnitude and resolving power are lower than the theoretical value. These two parameters Manufacturer binoculars Celestron telescope generally do not give the price, the user is best to measure what their own hands, which for better use of the double simple mirror helpful. On a clear, moonless night, when the Pleiades transit Celestron telescope monocular, binocular can be seen in Figure l darkest stellar magnitude would approximately equal to its limit and other stars. Just use binoculars can be separated in two sub-binary star angular distance is its actual resolution skills. Binary data can be found in the relevant catalog.

Binoculars refraction system is used, it can be divided into two kinds of Kepler and Galileo type. Simple Galilean binoculars structure Celestron telescope stores, small energy loss, a shorter barrel, the price is low, but Celestron telescope, it is generally not more than six-fold magnification, magnification and then increase, field of view will be rapidly reduced, the edge of the field of view becomes dark.
