There are several different brands making quality telescopes but if you’re looking for the best, you’re likely going to choose either Orion or Celestron. These two companies create some of the top telescopes on the market, as well as the accessories needed to enhance your astronomy skills. Of course, they are not identical in every way, which has many people comparing Orion vs Celestron to see which one is best to suit their needs. For more information on what these brands have to offer, check out our comparison sections below.
If you’re going to compare Orion vs Celestron, it’s a good idea to look at the brand as well as the products. The following sections cover the history of both of these companies, as well as their manufacturing processes and what types of products they have available to their customers.
Orion was founded by Tim Gieseler in 1975 in Santa Cruz, California. They sold telescopes, binoculars, and accessories until 2005 when they were purchased by Imaginova, at which time they also added a variety of non-Orion products to their catalog. In 2017, Orion was bought back by its employees, who focus on selling the best quality products possible with high attention to customer care.
As for Celestron, the owner and President of Valor Electronics, Tom Johnson, added an Astro-Optical division to his company to allow them to make telescopes in the early 1960s. Though they accomplished this goal, it wasn’t until 1970 that their telescopes became top sellers on the market. Their best-seller, the C8, was a compact model with a great low price but still a high-quality item that gained a great deal of attention. Celestron has continued to update and improve its models, adding several more to its arsenal, as well as a variety of other items that help them maintain their foothold in the scientific world.
Although both of these companies started in California, their products are not manufactured in the United States. Orion’s telescopes and other products are manufactured in China, while Celestron products are all manufactured in Taiwan.
Though Orion is best known for their telescopes, they also produce a variety of accessories for their products, like tripods, cases, and even binoculars. They also have items available at varying prices for any skill level, so beginners and pros can all shop at the same place without sacrificing their needs. They carry Cassegrain, Dobsonian, refractor, reflector, and even kids telescopes.
Celestron also has a variety of telescopes for beginners, as well as intermediate and advanced astronomers. These come in a range of prices, so you can spend as much or as little as you like. This company offers many different Schmidt-Cassegrain telescopes, as well as refractor and reflector telescopes. You can also find mounts, tripods, binoculars, scopes, microscopes, and many other items and accessories.

If you’re looking for a great telescope, there are several to choose from with these brands. The Orion SkyQuest XT6i and the Celestron NexStar 4SE are popular choices from these companies, though they aren’t identical in what they have to offer.
Even expert astronomers don’t want to struggle to use their telescopes. Luckily, the models available these days make them easy to use, though some are more user-friendly than others. Both of these models have an abundance of features that allow even beginners to get the hang of them in no time. The Orion SkyQuest XT6i includes an IntelliScope Computerized Object Locator, which shows you the coordinates of any object in the Trusted SourceThis Week's Sky at a Glance, September 10 – 18 - Sky & Telescope - Sky & Telescope The essential guide to astronomy skyandtelescope.org for quick location.
The Celestron NexStar 4SE takes this a bit further, allowing you to choose an object in the menu for the telescope to locate on its own. It even has a Tour function that gives you a guided tour of the best objects for the time and location you’re at.
These two telescopes are quite close in price at just under $500 each, so you can choose the one you like best without having to spend more money than you’re comfortable with. The Celestron does cost more if you want extra accessories, some of which the Orion already includes with their model.
The Orion model includes 2 Sirius Plossl 1.25-inch eyepieces, a finder scope, a 1.25-inch rack and pinion focuser, an eyepiece rack, a collimation cap, and their Starry Night software. The Celestron model includes their telescope only, though if you like, you can upgrade to their accessorized model, which includes a finder scope, camera shutter cable, 25mm eyepiece, tripod, and their astronomy software. This does add another $55 to the price, though, so keep this in mind.

For the viewfinder, the Orion SkyQuest XT6i uses a 6×30 correct-image, right-angle finder scope, which is included with the telescope. The Celestron NexStar 4SE uses a Starpointer finder scope, though you do need to purchase the accessories package to get it.
The optical tube on the Orion model has a length of 45.5 inches and a weight of 13.5 pounds. Of course, when the telescope is fully assembled, it is much heavier at about 34.4 pounds, so you likely won’t want to move it around more often than necessary.
