Types of telescopes

Binoculars can be divided into two main categories: Porro Prism. The Porro Prism is simple in structure, with higher light transmission than the Roof Prism, and has a wider objective distance, which makes the image more three-dimensional. Roof Prism is a relatively complex structure, requiring high precision, not easy to develop, the cost and price are higher; two sets of prisms into a straight line so that its volume is thinner, feel better, sealing performance is better, the recent focus is also shorter than the Pro type. Telescopes can usually be divided into the following four types: hand-held binoculars, monocular bird watching, giant binoculars, monocular astronomical telescopes.
