The Biggest Aperture for Your Money: Dobsonian Telescope They use a mix of mirrors and lenses which can bring with it both the advantages and disadvantages of both types of telescope. Lastly the compound telescope, also referred to as catadioptric, merges some of the features of both the reflector and refractor telescopes. Dobsonians offer significant aperture for a low cost, but they’re also pretty impractical due to their bulkier size. Then there’s the Dobsonian telescope, which is basically just a larger version of the Newtonian telescope but mounted on a fixed base that can be swiveled in both directions. Most of the big research telescopes, including the Hubble, use a reflector design. The mirrors in reflecting telescopes are easier to make in larger sizes, and thanks to this they usually have larger apertures and gather more light. This telescope is characterized by its use of curved mirrors instead of lenses as the main light-capturing device. The other main type of telescope is the reflecting telescope, also known as the Newtonian telescope or Catoptric telescope. They’re also easier to use, and one advantage of the refractor telescope is that the eyepiece is at the bottom end of the telescope rather than the top, which makes them more accessible to children, and means they can be used whilst sitting down, allowing the astronomer to use it for a longer duration. However, there are a few pros to this type of telescope for example, the lens in a refractor telescope requires less maintenance than the mirrors of a reflecting one and they don’t need to be collimated. Refractor telescopes are measured by the lens, and this means that price increases pretty quickly with lens size. The first telescope ever created was the refractor telescope, which is also the most commonly used, also known as the dioptric telescope. The larger the lens or mirror of the telescope, the more capable it is of gathering more light from the viewed object, which means the outcome is a brighter, sharper image. Telescope aperture size can roughly be described as the diameter of the primary light-gathering lens or mirror. While it’s easy for amateur astronomers to presume that the magnification power is the most important aspect of a telescope, it’s actually the size of the aperture that will have the biggest impact on the quality of your images, and of course, the price tag attached to the telescope.
