For views of deep-sky objects, star clusters and galaxies, opt for a reflector or a Schmidt-Cassegrain telescope.
If you’d prefer high magnification views of planets and moons, go for either a refractor or a Maksutov-Cassegrain design. Lower budget models will usually be reflector or refractor telescopes, while catadioptrics are more expensive. We recommend taking two main things into consideration: personal budget and what you’d prefer to view in the night sky. With all these variations, it can be tricky to figure out which telescope is best for you. Both types often come with a computerized GoTo system, which can work out which way the telescope is pointing and automatically adjust it to align with chosen targets. As such, the Schmidt-Cassegrain is usually better for astrophotography and for broader views, while the Maksutov-Cassegrain is great for sharp views of planets and moons. Schmidt-Cassegrains traditionally have bigger apertures, while Maksutov-Cassegrains usually have small apertures. This doesn't ruin the viewing experience, so don't let this put you off too much.Ĭatadioptric telescopes fall into two broad categories: Maksutov-Cassegrain and Schmidt-Cassegrain.
They do, however, tend to suffer from chromatic aberration, where bright objects appear to have a kind of halo. This type of telescope is ideal for beginners, offering a straight-forward assembly and a lower price point. Newtonian telescopes are good for a wide range of viewing targets and are often useful for astrophotography – however, they require a lot of maintenance and can be complicated to set up, whereas Dobsonians are more straightforward. Reflectors are usually either Newtonian or Dobsonian in design. Catadioptric telescopes correct some of the visual problems found in these older styles – such as chromatic aberration – but they tend to be a little more expensive. Refractors are great for highly magnified views of planets and moons, while reflectors offer better views of deep-sky objects, star clusters and galaxies. There are three basic types of telescopes: refractors, reflectors and catadioptrics. We've also included some buying advice, in case you need a helping hand with what to look out for. It's worth noting that although deals for telescopes at Best Buy can be a little harder to find than on other sites like Amazon or Walmart, they are out there and you'll find the best picks below. However, we've found the best telescopes at Best Buy and the deals they offer, so if you're in the market for a bargain, this guide is for you. While you will find some cost-effective telescopes and offers below, we do also have guides for budget telescopes for under $500, best telescopes for beginners and best telescopes for kids, if you're looking for a stargazing experience on a budget or to inspire a budding astronomer. If you know what make of telescope you want, or which you normally trust, then it might be worth checking out our specific guides for Celestron, Sky-Watcher, Meade and Orion telescope deals.
