With the beginning of spring migration it is time to consider investing in new binoculars. The key to a long and useful life for your binoculars is to follow the simple steps to protect against the unexpected.
The power of the optics is expressed as two numbers, such as 7 x 35. Compact binoculars are generally guarded with rubber padding, and they come with a case and hanging strip. All light transmitting surfaces are covered with multi-coating to increase brightness.
So if you have a pair of binoculars with 8x magnification, they should have an objective diameter of 40. You will find these to be quality binoculars that won't break should you drop them. Choosing a telescope is not an easy choice to make and is one that really needs research.
Under the right conditions, water drops could form inside the chamber, which could form permanent streaks on the lens when they evaporate. You will also need to buy an atlas of the sky suited for astronomy, and a guide.
