Product Description


In Part 1 of this three-part series, we discussed the advantages of using binoculars for astronomical viewing of the night sky and we talked about the different types of targets you can enjoy on clear, dark nights. At the conclusion of each section, I mentioned “binocular magnification considerations.” Here, we will get into that subject, as well as other characteristics of binoculars that make them better, or worse, for studying the stars. Then, in Part 3, we will look at different recommended sizes of binoculars for stargazing fun.

Binocular Numbers

Binoculars are assigned a pair of numbers that indicate the magnification of the optic and the diameter of the objective lens in millimeters. If you see a binocular that is listed as an “8x42”, the “8” is the magnification and the “42” is the diameter of the optic’s objective lens.

The magnification and objective lens size factor into how the binocular performs under different environments and lighting conditions.
