What do I need to 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.

How big of a telescope do I need to see the flag on the Moon?

The flag on the moon is 125cm (4 feet) long. You would require a telescope around 200 meters in diameter to see it. The largest telescope now is the Keck Telescope in Hawaii at 10 meters in diameter. Even the Hubble Space telescope is only 2.4 meters in diameter.

Is getting a telescope worth it?

So, yes, it is worth getting one. Many of these you can see in urban skies but, obviously, the darker the better. Get the best you can afford. Avoid very cheap scopes with the smaller (less than one inch diameter) eyepieces and jiggly mounts.

Can you see galaxies with a telescope?

Galaxies are some of the most distant objects we can observe. … Unlike planets and bright stars, galaxies fade out as they expand. Even if a galaxy is bright, the most you might typically see is its core with a 4-inch telescope. Don’t be discouraged though, this is where the fun really begins.

Can you see the footprints on the moon with a telescope?

In reality, all Earth-based telescopes have a much lower practical magnification limit around 300 times. This means that under typical seeing conditions from the surface of the Earth and using a large telescope, the footprints on the surface of the moon are something like 1,000 times too small to be seen.
