What should I know before buying a telescope?

What should I look for when buying a telescope?

The key spec for any telescope is its aperture, or the diameter of its lens or mirror. The bigger the better because a bigger aperture can collect more light and distant objects appear brighter. But this comes at a price, and bigger telescopes are also much less portable.

How do I choose a telescope for a beginner?

The bigger the aperture, the better the picture. That’s because the aperture determines the brightness and sharpness of the image. However, know that bigger aperture means bigger telescope. If you want to travel with your telescope, you may want to keep an eye on the size.

What magnification telescope do I need to see planets?

Experienced planetary observers use 20x to 30x per inch of aperture to see the most planetary detail. Double-star observers go higher, up to 50x per inch (which corresponds to a ½-mm exit pupil). Beyond this, telescope magnification power and eye limitations degrade the view.
