Maksutov-Cassegrain telescopes are not as popular as other styles, especially in the beginner market. They’re compact and powerful, but require more maintenance with regard to calibration and carry a higher price tag than the previously described telescope types. Schmidt–Cassegrain telescopes combine features of both reflector and refractor telescopes into a compact package that is suitable for a wide range of celestial viewing. That light then travels into the eyepiece at the back of the tube. A large lens at the front passes light through the tube toward a mirror in the back of the tube. This is the most common design found on consumer-grade telescopes. It then reflects that light to another mirror, which reflects the light once more toward the eyepiece. A mirror at the front of the tube gathers light. This telescope design sets itself apart with an eyepiece that extends vertically out of the tube, usually near the front. The mirror in the front is combined with a lens. This design has two mirrors inside the telescope: one near the eyepiece and one at the front. The eyepiece in a compound telescope is in the back. Each has a similar look, but they all work a little differently. Telescope designsįor amateur astronomers, five types of telescope designs exist: compound, reflector, refractor, Schmidt–Cassegrain and Maksutov-Cassegrain. You can think of the eyepiece like a magnifying glass, as it works on similar principles. Parts inside the eyepiece magnify the focal point, causing objects to appear closer than they really are. Using a ring or dial on the telescope, you can adjust the focus and sharpen your view. The optics inside the telescope then focus that light onto a point, allowing you to see the object. The aperture of the lens determines how much light travels through the lens a larger aperture allows more light to enter. ![]() Light from the object at which you’re aiming the telescope travels through the telescope’s lens and into the tube. Our list: The best telescopesĪ telescope collects light from a scene and focuses the light, which in turn makes faraway objects appear closer. For those not sure if they need a reflector, a refractor or something else, our guide below has the answers. ![]() Because of its excellent image quality and compatibility with add-ons and accessories, the Celestron NexStar 5SE Telescope is our top choice for anyone interested in the hobby who expects to continue exploring the cosmos for years to come. We checked out a range of telescopes to find the best ones for all skill levels. In fact, aspiring astronomers can directly observe the craters of the moon, Saturn’s rings and even deep space nebulae from the comfort of home using affordable telescopes that are quick to set up, portable and even compatible with smart devices and consumer cameras. While the tools that the pioneers of science used were cumbersome and difficult to see through, modern consumer telescopes are compact, powerful and simple to operate. Since the dawn of time, observing the night sky through a telescope has filled human beings with wonder, allowed explorers to navigate into uncharted lands and sparked the imaginations of scholars who would go on to formulate our very understanding of our place in the universe.
