 The first astronomical telescope was a triple telescope made by Galileo using the method of telescope making.  It was later improved to magnify the telescope 20 times at once. He was able to see the round face of Jupiter and  the craters of the moon. In 1610, he used a telescope with a magnification of 30 times to observe four moons of  Jupiter and see the circle of Venus. Because Galileo improved the performance of the telescope, and used it to observe the stars,  the moon, Venus, and the sun, and published the first observations, it is precisely he who invented the astronomical telescope.   Suggestions for buying: Telescopes for Adults    The astronomical telescope is an important tool for observing celestial bodies.

 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 che...

  A telescope is an optical instrument that uses lenses or mirrors and other optical devices to observe distant objects.  It uses the light refracted through the lens or reflected by the concave mirror to make it into a small hole and converge to image,  and then through a magnifying eyepiece and be seen, also known as the "thousand mile mirror".     The first function of a telescope is to magnify the Angle of distant objects so that the human eye can see details at smaller angular distances.  The second function of the telescope is to beam light collected by the objective lens, much thicker than the diameter of the pupil (up to 8mm),  into the human eye, allowing the observer to see faint objects that would otherwise be invisible. In 1608, Hans Liebosch,  a Dutch optician, accidentally discovered that he could see distant objects with two lenses, and was inspired to build the first telescope in human history.  In 1609, Galileo Galilei, a Flo...
