How do telescopes work?


what is the purpose of a telescope?

Contrary to popular belief a telescope does not magnify objects.

A telescope functions by gathering light into it’s optical tube and then, by employing a lens or mirror, focuses the light into a clear image that can be seen through it’s eyepiece.

While magnification is still plays a role, think of it like this…

The mirror is like a digital picture on your computer, and magnification is like you pressing the “zoom in” button on that picture, it doesn’t matter far you can “zoom in” if the picture (the mirror) is low quality, you’ll just be zooming in on a fuzzy image.

The higher quality of mirror, the more detail you can magnify.

Also, the bigger the optical tube of a telescope, the more light it can collect, that’s why higher-end telescopes look more like a large bucket than they do to the common cultural representation of a telescope.

These thicker telescopes are optimal because a mirror can only be reflective up to a certain point and when it hits that limit, it needs to be larger in size (aperture) in order to get the greatest detail possible out of the sky.

Think of a bucket collecting raindrops, with raindrops in this example being light particles, you need a big bucket to collect a lot of raindrops.


Just keep in mind, that the purpose of a telescope is to collect light, and the more light it collects the better image resolution and with better image resolution, the more you can magnify it. If you remember this when buying a scope, you’ll have a more enjoyable observing experience.

There’s a lifetime of observing to do with a telescope of objects you can’t see with the naked eye (even with just high-powered binoculars) and all the astrophotography myself and others do with our scopes would still not be enough to catalog everything that’s out there.
