The refracting telescope has been around for a few hundred years. One of the first models of this telescope is known as a Galileo refracting telescope. Although much improved on, refracting telescopes are still very popular. If you have caught yourself staring into your telescope and wondering “How does a refractor telescope work” you might be amazed at the simple answer.
The Two Main Parts Found In A Refracting Telescope
Every refractor telescope has an objective lens inside. This objective lens will vary in size depending on the telescope. When you point the objective lens at an object that you see in the night sky the lens will gather the light given off by that object. As the objective lens gathers the light from the object it will bring it to a point on the lens. This point is called a focus. The larger the objective lens in your telescope is the more light it will be able to gather from objects in the night sky. The result will be more detailed viewing of celestial objects. So the next time you wonder “how does a refractor telescope work” you will know that the first piece of the answer is the result of the contributions made by the objective lens.
The second part of the question “how does a refractor telescope work” lies within the eyepiece. The second lens that makes up a refractor telescope is known as the eyepiece lens. This is an interchangeable part of a refractor telescope that allows the astronomer to change the magnification on the object that he or she is viewing or to add filters to bring out certain details in a particular object like the red spot on Jupiter. The eyepiece lens works in a similar fashion to a magnifying glass. The object lens gathers light from an object into a point called the focus and then the eyepiece lens magnifies the focus so you can actually see it. So when asking “how does a refractor telescope work” you will now understand that the objective lens gathers the light into a point called a focus and the eyepiece lens magnifies it. Hence, you are able to see distant objects in the night sky with great detail through a fairly simple device called a refractor telescope.
Although a refractor telescope might be fairly simple by design that does not equate to an inexpensive price tag. The lenses inside a refractor telescope are crafted with great precision. Poor lens quality can result in imperfection in the image you are viewing.
