Telescopes

 When it comes to telescopes, many people think they are out of reach, but in fact, you don't need a lot of foundation and you don't need a lot of money to enjoy stargazing.

   The general telescope is divided into three parts, the mirror tube, the equator and the tripod

   There are two general types of telescopes, refracting and reflecting.

   First of all, the refraction type, the principle is the same as the microscope, two concave lenses, is the most primitive telescope, 

the general comparison of the basic telescopes are refraction type, such as star Tron 80eq, 90eq and so on, but this kind of telescope will often have color difference, according to the quality of different degrees.

   Then there is the reflective telescope, which uses a concave lens to magnify the function. 

This kind of telescope is often "short and thick", with a large aperture. Because the concave lens only needs to consider one side, the price is also cheap, and there is no color difference at all.

   And then there's the equator.

   Suggestions for buying:Telescopes

   There is a kind of equatorometer similar to the camera tripod. This type is easy to operate, but the accuracy is very poor, 

and it is difficult to align the celestial body, and the tracking is more troublesome. It is made by the mirror under 500 yuan. In fact, there are some high-end mirrors that use electric tracking, such as the Startron Evolution

   And equatorial is normal, it is used to find and track objects, relative major, with the general competition, can be equipped with electricity, after the installation is more convenient, 

need not to adjust manually, but suggest beginners don't need to install with electricity, one is the first of the mirror must be not worth, the second is should be familiar with the principle and the operation
