As an example, a telescope with a 10-inch aperture will make distant objects appear sharper than one with only a five or six-inch aperture.Ī telescope's power is another important piece of the puzzle for determining the degree of mangification it will offer. The diameter of a telescope's aperture is directly proportional to the level of detail you see when you look through it. The aperture determines the degree of brightness and sharpness you see through a telescope. One of the most important aspects of a telescope is its aperture through which light will travel. A majority of telescopes focus on detecting electromagnetic radiation. This is accomplished through the use of either an arrangement of lenses or, as worded in the Oxford English Dictionary, an arrangement of both curved mirrors and lenses, by which rays of light are collected, focused, and the resulting image is magnified. On the same parallel, with the invention of a unique tool like the telescope, our definition of what it means to think outside the box changes dramatically.īy definition, a telescope is an optical instrument with a primary purpose of making distant objects appear close and easy to see. Without an awareness of what's around you and how things appear, you wouldn't begin to suspect that perhaps the Earth was round due to the observation of moon phases over time and the spherical shape of the Earth's shadow that is cast on the moon's surface. If humans had given up on curiosity, then it's possible everyone would still believe the Earth is flat. The more scientific breakthroughs that occur, the less inclined I'd be to believe human curiosity is ever satisfied. By itself, curiosity does not provide all the answers, but it does encourage imagination, the desire to hone one's thoughts, the desire to grow, and to experiment with technology that will serve that curiosity. Though just the first step, this very curiosity has allowed technology to evolve along with it. Humans have always been curious about the world around them. And the 16-inch Meade Lightbridge just isn't that accessible any more, so we swapped it out for the Meade 12-Inch LightBridge instead. The Orion SkyQuest XX16g, for example, is a bit pricier than its 14-inch brother, but the difference its wider aperture makes in your focal ratio is more than worth the increase in price for a real pro stargazer. Some of the models on our previous list were replaced by their partners in brand and lineup, just sized up or down in accordance with the best value offered and the availability of certain models. In the place of the Powerseeker, we included what might be a holy grail model for many amateur astronomers in the Meade Instruments LX850, whose astounding light gathering capabilities, in conjunction with its surprising portability, make it one of the most useful scopes around. It's a fine model for beginners, and we've still included some offerings that could be considered entry-level, but scopes like the Orion SkyScanner 10012 are just undeniably better, with superior optics and build quality. Revisiting this list, it occurred to us that we already have a ranking dedicated to beginner's telescopes, which made us less inclined to keep any bargain items on this list, like the Celestron Powerseeker 70 we took off. To be fair, this isn't an inexpensive model, but for its specs, it's a steal. It's also worth noting that you rarely see refracting models this size, principally because the labor intensity involved in grinding objective lenses this size to the precision needed for astronomy often raises the cost too high. Now, at first glance, you might not realize just how big this thing is, but it's massive. One particularly nice feature of the NG is the red backlight on its controller, which is ideal of you're operating it frequently on a single outing and don't want the light from its screen or keypad to impact your eyes' ability to see as much of the sky as possible.Īnother newcomer to this list can be found in our special honors section, where we've added the Sky-Watcher Esprit 150mm ED Triplet APO Refractor. While there wasn't a lot of action in this category, we did see fit to swap out an old Meade model for the Meade Instruments StarNavigator NG 130MM, which is a little more compact and portable, and that's a lot more user friendly, even if it doesn't quite have the resolving power of the other.
