![]() The prices depend on the maker and the technology. If you have more to spend, you can look into computerized telescopes, ones with tracking devices, larger lenses, or higher magnification rates. For those looking to set up a scope in their backyard for clear nights, roughly $200-400 will get you a great quality starter scope. Prices on these scopes vary, but considering the difficulties they present for makers of large scopes, the versions available to the public tend to be within a reasonable price range. Also, the glass lense itself will eventually dip thanks to its own weight because it can only be supported by its ends. Refracting lenses don’t allow ultraviolet light through them at all, and the thickness of the lense determines the clarity of the other lights that pass through. The largest refractor telescope is at Yerkes Observatory, and measures in at 102 cm.Ĭhromatic abberation is one of the most common downfalls light wavelengths bend differently, and because of this, you may see a rainbow effect around the object you’re viewing through the lense. Few and far between, these drawbacks are the reason that most refractors are for commercial use and small observatories. There are very few large-scale refractors used for research because of the disadvantages these scopes carry with them. Also, images seen through the telescope are sharper and steadier thanks to the tube being immune to changing temperatures and climates. It’s sealed off, so you don’t have to worry about cleaning it often, if ever. The benefits of choosing a refractor over any other type of scope start with the placement of the lense. This type of scope tends to be tiny, but it’s perfect for looking at the moon and planets within this solar system. Scopes used on rifles and other guns are refractors, as well as the small telescopes you find at general department stores. Galileo and others who designed the original technology found this method to be the easiest to make. ![]() “Refracting” literally means to bend and the first models of telescope were refractors. Another name for this type of scope is a “dioptric telescope”. The light then bounces off a small mirror into the eyepiece, where the viewer sees a larger, sharper image of the object they’re looking at. In simple terms, a refractor telescope uses a glass lense at its end to gather light, and as it travels through the telescope, the light bends.
