Refractor, Reflector, and Dobsonias Telescopes

January 12 @ 8:00 am - 5:00 pm EST

If someone calls a name like Nicolaus Copernicus, Galileo Galilei, and Sir Isaac Newton the bell will definitely ring. The brilliant minds of the past that changed the world in the field of Astronomy as we know it now will never be forgotten. Each of these men discovered amazing things about the universe except Copernicus; the findings that changed everything were done with a telescope. As soon as we look today, in the 21st century, with the remarkable advances in the field of astronomical telescopes and so many options in the market it is difficult to choose the right telescope for a novice astronomer. With a wide selection to choose from such as light telescopes, repetitive telescopes, Catadioptric telescopes, and Dobsonian telescopes and other alternatives may be difficult for budding emerging astronomers to choose which type of telescope is the right Optical Mechanics for them. This brief introduction to the history of the major telescopes on the market today should give a budding astronomer what to expect, yet this is not the best telescope guide, but moreover a worn-out history study for each telescope.

Refractor Telescope

Opposite telescopes, also known as retractable telescopes or dioptric telescopes, bend the light to cause parallel radiation to focus. The design of the refractor telescope was widely used in spy glasses before being used in star televisions. The telescope refractor was the first telescope to be developed. It uses a 'glass lens' as a way to convert light rays to create an image. After all, the first opposing telescope in existence was none other than Galileo Galilei. He invented the first refractor telescope with one large glass lens as a target and a small lens as an eyepiece or focus area. In order to re-illuminate the glass lens had to be completely molded depending on the required image size. The focus area will have a glass lens opposite the opposite angle of view to keep the image from looking down. This design, one of the first light telescopes, has come to be known as the Galilean telescope.

Though gorgeous in the galaxy of the Galilee, there is always room for improvement, which is why in 1611, astronomer Johannes Kepler developed another opposition telescope based on the telescopes of the Galilean telescope. The Keplerian Telescope, as it is known, used convex lenses as opposed to Galileo's version of convex lenses.

This actually gave the viewer a much wider viewing spot and much-needed eye relief. Too bad the image would have been distorted. Another disadvantage of the refractor telescope was its lack of ability to filter fixed radiation. This deficiency has resulted in the development of repeating achromatic telescopes and apochromatic refractors. Achromatic refractor telescopes are well described. They are designed to display a colorless image to minimize contrast. The apochromatic refractor binoculars, on the other hand, are designed to deliver three colors. The viewer will be able to see the red, green, and blue hues with a slight deviation that makes the apocalyptic telescope very attractive in its time.

Fast forward to the 21st century and refractor telescopes have advanced so much that with the right telescope, viewing a clear picture of Pluto with lenses is not possible. And with the advent of technology, goto refractor computer telescopes are now commonplace.
