Refractor vs reflector telescope8/3/2023 Through links on our site, we may earn an affiliate commission. Stealth Optional is supported by its audience. They'll require more upkeep, but the pay off means that you won't get an chromatic aberration, and you'll be able to see stars and galaxies much brighter too. You may get some chromatic aberration, but that shouldn't be an issue if you're just starting out.įor those who want something a bit more technical and enjoy the process of adjusting, maintaining, and just generally 'tinkering', a reflector telescope could be the best one for you. Differences Between A Schmidt-Cassegrain And Reflector Telescope. If you're a beginner, we'd probably say starting off with a lightweight, refractor telescope could be the best way to go, as they can be moved easily and don't require much technical know-how to setup and maintain. Choosing either a higher quality lens or ensuring that the mirror setup is more optimal would be a wise place to start, but there will be many good quality telescope from either side at more affordable price points. Of course, budget is something you'll want to factor in as both types of telescopes have their advantages and disadvantages at different price points. Reflector vs Refractor Telescopes: Which Should You Buy? If you're new to star-gazing, a reflector telescope may have a bit of steep learning curve, especially as you'll need to collimate (or adjust it) before use to ensure it's giving you the best image possible. That means more cleaning, more care, and more chance of dirty mirrors and unclear images. While the open tube setup is great for capturing light, it does mean that your reflector telescope is exposed to the elements.

Using this combination can be expensive, so at the lower cost end of reflector telescopes you may find that they use spherical mirrors instead. Parabolic mirrors are generally used as the primary mirror, with hyperbolic mirrors designed to accurately focus light from one focal point to another. There are a few types of mirrors that can go into a reflective telescope: parabolic, hyperbolic, or spherical. While a reflector telescope may seem like an obvious choice, the quality of the image will largely be down to the mirror used. Reflector telescopes are said to be better for seeing galaxies on the whole. They also tend to be a little smaller, as unlike with refractor telescopes, you don't need a longer tube to focus the light. One big advantage is that you won't get any chromatic aberrations when using a reflector telescope. The tube itself is more 'open' than with a refractor telescope, with the best reflector telescopes having very large mirrors to capture as much light as possible. Because of this, you'll often see the eye-piece placed at different locations on the tube, rather than sitting at the end. Reflector telescopes eliminate the chromatic aberration that plagues all refractor telescopes but refractors will generally have a clearer overall image quality for objects that are closer to the viewer. Reflector telescopes, as the name suggests, work by using one or more mirrors to focus light.
