The Best Telescopes Under $200

76mm is small, and this page is not going to pretend otherwise. What it is not is a toy: the mirror is real, the mount is a proper Dobsonian, and it will show the Moon's craters and Jupiter's moons.

Two times 76mm gives 152x of useful magnification. Celestron publishes 180x. Either figure demolishes the 525x printed on the box of the department-store scope sitting beside it at the same price.

The f/3.95 focal ratio is very fast, which is hard on a spherical mirror and hard on cheap eyepieces. Expect softness at the edge of the field and do not expect much above about 60x to 75x in practice.

The right way to think about it: this is a lot better than nothing, it is enormously better than a 60mm toy scope on a plastic tripod, and it is meaningfully worse than the 130mm tabletop Dobsonian that costs roughly three times as much.

This telescope is on the site because it is one of the best-selling beginner scopes there is, and because buying it without understanding it is how a lot of people end up disappointed.

Start with the arithmetic. 127mm of aperture gives 254x of useful magnification at the 2x rule; Celestron publishes 300x. Retail listings for this model have long advertised figures far above both. The optics do not change because a shorter eyepiece is fitted.

The design detail that matters: Celestron's own optical design line says spherical primary mirror, and the tube is far shorter than a 1000mm focal length would normally require. That combination is achieved with a corrector lens in the focuser tube, and the arrangement is much more sensitive to collimation than a straightforward Newtonian.

The mount is a German equatorial, which is the right tool for tracking but is genuinely confusing on night one. It has to be roughly polar aligned before its motions make sense, and a gift recipient who has never seen one will usually assume it is broken.

3.3 pounds for the whole kit including the tripod is the entire pitch. Nothing else here goes in hand luggage.

The optics are the same 70mm as the AstroMaster LT but at f/5.7 rather than f/10, so the tube is much shorter and the widest field is much wider. That is good for landscapes and star fields and less good for the planets, where the shorter focal length shows more false color.

Two times 70mm gives 140x of useful magnification and Celestron publishes 168x. The published Dawes limit of 1.66 arcseconds means no Cassini division and no tight doubles.

The tripod is the weak link and everybody who owns one says so. It is a photo tripod carrying a telescope, and above about 60x it shakes. If you already own a decent tripod, use that instead.

70mm of refractor aperture puts this at the floor of what is worth owning, and the same arithmetic applies as to every other 70mm on this site: 140x of useful magnification at the 2x rule, and a Dawes limit of 1.66 arcseconds.

The panhandle mount is the differentiator. A single handle that moves in both axes is far more intuitive for a child, or for an adult who has never used a telescope, than either a slow-motion alt-azimuth head or an equatorial one.

National Geographic publishes a 400mm focal length, which at 70mm gives f/5.7, and advertises 16x, 40x, 48x and 120x. Those four figures check out exactly against 25mm and 10mm eyepieces with the supplied 3x Barlow, and the top one sits under the 140x this aperture supports — which is not what the bottom of this market usually does.

As a gift this earns its place on presentation and on the mount. As an instrument it is a 70mm refractor, which means the Moon, the bright planets and not much else.
