How We Research

Updated on

Every guide on Telescopes Geek starts with one question: will this telescope work for the person shopping for it? That depends on what you want to see, where you will set up and how much you want to carry.

Here is how we answer it.

1. We start with what you want to see

The moon and bright planets need a different scope than faint galaxies. A scope for a balcony needs different traits than one for a backyard.

We say what a telescope can and can't show, in plain words. We skip hype like "300x power", because the usable magnification depends on the size of the lens or mirror.

2. We compare specs and features

We look at the aperture (the width of the lens or mirror), focal length, scope type and mount. We note the tripod, the eyepieces and the finder that come in the box, and the weight.

For app-guided scopes we check what phone and app the maker says you need. Celestron, Sky-Watcher and other brands describe their scopes in their own words, so we name the brand for each claim.

3. We look at buyer feedback

We read what buyers report after they set a scope up. We look for patterns, like a wobbly tripod, a hard-to-focus finder, missing parts or a mount that frustrates beginners.

One angry review doesn't sink a product. A pattern does.

4. We score each product

Our score weighs specs, features and buyer feedback against what you're shopping for. A scope that suits one reader may score lower in a guide written for another.

Scores spread out on purpose. A 10 is rare.

5. We keep pages up to date

Models change and some disappear from stores. Makers sell near-identical scopes under close names, so we check the model number and what comes in the box.

We skip unknown listings with no track record and any telescope with a known recall. When we update a guide, the "Updated on" date at the top changes with it.

What our picks are not

Our picks are research, not lab tests. We don't claim to have used every telescope we cover.

Never look at the sun through a telescope, binoculars or finder without a solar filter made for it. Solar viewing can cause permanent eye damage, and we don't cover it.

We label maker claims as the maker's claims, and we never promise what you will see on a given night.
