We've rounded up the best telescopes at Walmart with some big discounts on top brands including Celestron.
When it comes to buying a telescope you need to consider two main factors: Your budget and what you're wanting to view. There are three main types of telescopes out there, and figuring out what you want to view will help you decide what type of telescope you will need. There are refractors, reflectors and catadioptric telescopes.
For beginners, refractor telescopes are often a popular choice due to their easy to maintain and use style. They're often mounted to alt-azimuth mounts so they're straightforward to use and the mounts themselves are easy to manufacture so the price tends to be cost-effective too. They're best used for focussing on specific targets like moons and planets due to the fact that they're good for showing high-magnified and high-contrast images.
Reflector telescopes tend to have larger apertures and are better for low-magnification targets like nebulas and galaxies. You get two types of reflector telescope: Dobsonians and Newtonians, although there’s some crossover between these. In brief, though, Dobsonians are easier to maintain and often found attached to the alt-azimuth mount.
Finally, catadioptric telescopes fix issues found in both of the above types of scope – such as chromatic aberration and the coma effect – and they are typically equipped with a GoTo system. These systems are essentially mini computers that align your telescope to particular night sky objects. You get two types of catadioptrics, the Schmidt-Cassegrain and the Maksutov-Cassegrain.
