![]() What this means is that the mirror won’t lose its original quality or in the worst-case scenario ‘break’, but its ‘edge’ will gradually get duller. Under normal circumstances, the wind or smaller chunks of dust debris wouldn’t be able to damage the mirror per se, but they could destabilize and unbalance the telescope. ![]() Most reflectors feature the open-end design, which basically means that their mirrors are highly exposed to environmental ‘hazards’, such as humidity or dust particles. Even though they’re not so readily available and are pricey to the boot, this is the only type of mirror that can provide a clear, vivid image of distance space objects with ease. The type of a mirror that is the least commonly used due to its sky-high price tag is the hyperbolic mirror. Sadly, most parabolic mirror models aren’t capable of dealing with problems of chromatic aberration (blurring). Parabolic mirrors are typically made of superior quality in comparison to spherical mirrors – they gather more light and ‘reflect’ it back with more consistency. However, the downside of this mirror type is that they tend to blur the image somewhat, rendering reflectors equipped with them virtually unusable for deep space observation. Now, spherical mirrors might be flimsiest, but they reflect light pretty reliably and nicely. The cheapest option (which most manufacturers rely on) is utilizing spherical mirrors. Optical qualityĭepending on what type of mirror is used, a reflector will provide a different type of optical performance. Many amateur astrophotographers prefer the reflecting telescope, and there’s a few reasons why. While lenses are best suited for ‘low-range’ observation, mirrors allow more light to pass through, which in turn makes Reflectors ideal tools for observations of the deep space. Reflectors are ‘lens-less’ telescopes that utilize convex mirrors that reflect light. This is, basically, a type of telescope that is closely related to Newtonian telescope – it belongs to a larger group of catoptrics telescopes along with Cassegrain telescopes, Crossed Dragone telescopes, Gregorian telescopes, Wolter telescopes, and others. Reflecting telescopes are sometimes referred to as ‘reflectors’. Let’s look at both of them a little closer to find out more. But, there are advantages to opting for a refractor over a reflector too. The truth is that both telescopes have their advantages, and there are areas where they are similar too – optical quality isn’t always dictated by telescope type, for example. Typically, a refractor telescope will have a smaller size and aperture, which means that they gather less light, and therefore they are typically powerful. Though they work differently to each other, they’re designed with the same purpose in mind – to gather and focus the light from the night sky above us. This is where refactor telescopes differ, as they are only made up of lenses, and you can find them at the back of the telescope tube. In comparison to this, a reflector telescope uses a primary mirror (objective) in combination with a secondary mirror (reflecting mirror).Ī reflector telescope is largely made up of mirrors, and you’ll find the focuser and eyepiece on the top of the telescope tube. A refractor telescope relies on using an optical lens to gather enough light to focus the light through to the eyepiece. But, let’s take a look at the differences between reflectors and refractors.Īt its simplest, the answer is that they use a different method of to produce an image. Here’s my list of the top telescopes currently available if you’re in a rush. Getting the right telescope isn’t easy, but fortunately with the internet, you can research beforehand and find out which model to opt for. Reflecting vs Refracting Telescopes – Which to Choose After this, you should know the difference between refracting telescopes and reflecting telescopes, which can help you know which one would be better for your needs. So if you’re in the market looking for the most essential part of your astronomy rig, we’re here to help you decide which to choose. However, the majority of people mainly use reflectors and refractors when you’re just starting out. Reflecting and refracting telescopes, along with Catadioptric telescopes, are the three main telescope types.
