Compare Telescopes Side by Side
Choosing a telescope comes down to a few concrete numbers: aperture (the objective lens diameter), magnification range, and how the scope mounts and tracks objects. This comparison tool pulls real specs from the telescopes in our database and shows them side by side, so you can see those differences in a single table instead of flipping between product pages.
Sort by aperture to find the best light-gathering for your budget, or sort by magnification to match a scope to your primary target, whether that's the moon, planets or deep-sky objects. Mount type matters too: alt-azimuth mounts are easier to set up for casual observers, while equatorial mounts let you track objects as the Earth rotates. The table shows the focus type as well, so you know whether a scope uses a rack-and-pinion or a Crayford focuser before you buy.
Price and buyer data sit next to each spec so you can weigh cost against capability without any guesswork. If you want a starting point, filter to your price range and then sort by aperture. Larger aperture almost always means more detail, and the numbers here make that tradeoff concrete.

Frequently asked questions
What does aperture mean and why does it matter for telescopes?
Aperture is the diameter of the primary lens or mirror, measured in millimeters. A larger aperture collects more light, which means brighter, sharper views of dim objects like nebulae and galaxies. For lunar and planetary viewing the gain is less dramatic, but more aperture still resolves finer detail. The comparison table lists objective lens size for every scope so you can sort by it directly.
How do alt-azimuth and equatorial mounts compare?
An alt-azimuth mount moves up-down and left-right, which is intuitive and quick to set up. An equatorial mount is tilted to match Earth's axis, letting you follow a star with a single slow-motion control rather than adjusting two axes at once. Equatorial mounts are better for long observation sessions or astrophotography. The mount column in this tool shows which type each telescope uses.
What magnification should I look for in a beginner telescope?
Most experienced observers recommend keeping magnification under 50x per inch of aperture as a practical ceiling. Higher magnification dims the image and amplifies any vibration. For a 70mm scope that works out to roughly 140x maximum useful power. The comparison table shows the magnification specs listed by sellers, which you can weigh against aperture to spot good matches.
Are refractor or reflector telescopes better?
Refractors use glass lenses and tend to give sharp, high-contrast views with little maintenance. Reflectors use mirrors, which deliver more aperture per dollar but occasionally need the mirror realigned (collimated). Neither is universally better. The right choice depends on your budget and how much setup you want to do, and the specs in this tool help you compare specific models across both types.
Can I trust the magnification listed on a telescope box?
The magnification figure on the box is often the theoretical maximum with the included eyepiece, not a realistic everyday number. Actual useful magnification depends on aperture, atmospheric conditions, and optical quality. Use the specs in this comparison as a starting point, then read buyer reviews for real-world accounts of how much detail people actually see.
