This list of the largest optical reflecting telescopes with objective diameters of 3.0 metres (120 in) or greater is sorted by aperture, which is a measure of the light-gathering power and resolution of a reflecting telescope.

2024年1月8日 · The Orion SkyQuest XT8 Classic is a large reflector telescope that offers the most value for money. It comes with a big 8” parabolic primary mirror that collects 78% more light than a 6″ mirror, so you get a significant increase in the ability to see details when observing.

2025年1月22日 · What we found is that these range from very powerful but regular-sized telescopes, to the ridiculously large bigger-than-a-person model. If you are looking for the most powerful telescope you can buy off the shelf to use at home, then it’ll …

2021年11月28日 · The Orion SkyQuest XT10 Classic Dobsonian is one of the most affordable “large aperture” telescopes for visual astronomy. With its powerful 10” primary mirror, it offers a ton of bang for the buck. And it’s still portable enough to bring with you camping or to a dark-sky location. Keep reading below for our full review.

2018年5月1日 · 10” PRIMARY MIRROR: Our Newtonian reflector telescope is equipped with a large, 10-inch primary mirror for stunning views of planets, galaxies, nebulae, and more. BUILT-IN COOLING FAN: Cool the primary mirror to the ambient outdoor temperature faster so you can enjoy the sharpest views sooner.

2007年2月24日 · NEWTONIAN REFLECTOR OPTICAL DESIGN: With a large, 130mm aperture, the AstroMaster 130EQ can gather enough light to see our Solar System and beyond. View Saturn’s rings, Jupiter’s Galilean moons, the Moon's craters, and more. EASY TO SET UP AND USE: This is a great telescope for kids and adults to use together.

This list combines large or expensive reflecting telescopes from any era, as what constitutes famous reflector has changed over time. In 1900 a 1-meter reflector would be among the largest in the world, but by 2000, would be relatively common for professional observatories.

2023年10月3日 · If you want to build your own telescope, it’s likely going to be a reflector. If you’re willing to perform collimation, be content with obstruction, and look for quality optical features within your budget, a reflector will work out great for you.

The Orion StarBlast 6 is an excellent telescope, whether you’re a beginner or looking for a “grab n’ go” or wide-field instrument to accompany a larger telescope. I highly recommend it, though it does have a few compromises typical of a budget instrument in its price range.

There are a number of advantages to using a reflecting telescope, as they're more cost efficient than a refracting telescope, which requires large lenses to focus light. They're also great for viewing distant objects with a bright image.
