Quick answer: How Do You Know If A Telescope Is Good?

What is a good magnification for a telescope?

A useful rule of thumb is that the maximum magnification your telescope can handle is around 50 times the telescope’s aperture in inches.

Any higher and the image gets too dim and blurry.

So, a 6 inch scope can magnify up to 300x, while an 8 inch scope can magnify 400x..

What can you look at with a telescope?

While watching the Sun can be done safely with a telescope, you need dedicated equipment to do so.The Moon. The best object for examination with a small scope, bar none, is Earth’s Moon. … Jupiter. … Orion Nebula. … Andromeda and Triangulum galaxies. … Large and Small Magellenic Clouds.

What is the best type of telescope for beginners?

After spending five months gazing at the stars while testing 10 telescopes, we think that the Celestron NexStar 5SE is the best telescope for beginners. It offers enough power and an efficient amount of gathered light that allows you to see deep-sky objects.

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 the flag still on the moon?

Images taken by a Nasa spacecraft show that the American flags planted in the Moon’s soil by Apollo astronauts are mostly still standing. The photos from Lunar Reconaissance Orbiter (LRO) show the flags are still casting shadows – except the one planted during the Apollo 11 mission.

Who owns the moon?

The Outer Space Treaty means therefore that – no matter whose national flags are planted on the lunar surface – no nation can ‘own’ the Moon. As of 2019, 109 nations are bound by the Treaty, and another 23 have signed the agreement but have yet to be officially recognised.

Has anyone died on the moon?

As of 2020, there have been 14 astronaut and 4 cosmonaut fatalities during spaceflight. Astronauts have also died while training for space missions, such as the Apollo 1 launch pad fire which killed an entire crew of three.

How powerful does a telescope have to be to see the rings of Saturn?

Viewing Saturn’s Rings The rings of Saturn should be visible in even the smallest telescope at 25x. A good 3-inch scope at 50x can show them as a separate structure detached on all sides from the ball of the planet.

How much magnification do you need to see Jupiter?

Generally a magnification of 30-50x the aperture of your telescope (in inches) works well on nights of average seeing. So if you have a 4-inch telescope, try 120x to 200x. If you have razor sharp optics and steady sky, you can get away with even more magnification.

Can I see a galaxy with my telescope?

If you want to observe galaxies — and I mean really get something out of the time you put in at the eyepiece — you have to use a telescope with an aperture of 8 inches or more. Bode’s Galaxy (M81) glows brightly enough to show up through binoculars, but the larger the telescope you can point at it, the better.

Can you look at Sun through telescope?

The safest way to look at the Sun through your own telescope is NOT to! Not only could you damage your eye, but you can also damage the lenses in the telescope.
