You can get a pair of Cheap Binoculars, also known as field glasses for under $100. Binoculars are two telescopes connected together. Having two pieces helps depth perception.
Telescopes have been around for a while, ever since the 17th century. It didn't take people long to start connecting telescopes together, creating binoculars.
In the late 1800's, a prism type of binocular was created that enabled greater depth because the eye pieces were farther apart. Prism Binoculars also allowed more magnification.
The cheapest kind of prism binocular is the porro prism binocular. These are more affordable than other kinds and still have a great picture. One downside is that they need to be adjusted from time to time.
A more expensive kind of prism binoculars is a roof prism binoculars. These binoculars don't need be readjusted as much as porro prism binoculars. These binoculars are lighter wieght and smaller.
UV coating on binoculars is very important because it reduces the amount of light that is reflected inside of the binoculars. Reflected light inside of the binoculars causes the image to become hazy.
General focus binoculars can be focused by moving the wheel in between the two eye pieces. Independent Focus Binoculars require that both
eye pieces are focused independantly.
High powered binoculars move a lot when hand held. This is very disturbing when trying to look through your binoculars. Some high powered binoculars have a image stability device that cuts down on the changes in movement. This is a great feature, but it is very expensive.
Tourist attractions usually have coin-op binoculars. They offer a really good view of the surrondings for people that don't have their own binoculars.
Military Binoculars are normally 7x magnification. The elements of the outdoors require that military binoculars be extra sturdy. Military Binoculars are almost always independant focus because it is more reliable than general focusing. Military Binoculars sometimes have special coatings that reflect laser beams. Sea Binoculars are coated to block out the sun and to protect agianst salt.
Astronomy Binoculars are used for viewing the night time sky. You can see a lot more stars with binoculars than with your naked eye. While some people use high powered binoculars for astronomy, binoculars with a large field of view are better if you need help finding things.
