Question: How strong does a telescope have to be 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 powerful does a telescope have to be to see the Saturn rings?

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

How big of a telescope do I need to see Jupiter?

A well-made 5-inch refractor or 6-inch reflector on a sturdy tracking mount is really about the minimum for serious Jupiter observing. Larger instruments will allow scrutiny of fine detail and subtle low-contrast markings.

What is the most powerful telescope for home use?

Most Powerful Telescopes IN-STOCK

  • Meade 8″ ACF LX200 – 8-inch Advanced Coma-Free telecsope with GOTO fork mount.
  • Celestron AVX 7″ – 7-inch Maksutov Cassegrain OTA combined wtih Celestron’s equatorial Advanced VX Mount (great for astrophotography)

How big of a telescope do I need to see Mars?

Any telescope will work for Mars, but the bigger, the better. A 4-inch refractor or a 6-inch reflector are the recommended minimum. Apply high power (175× or more), and wait for a night with steady seeing, when the Martian disc is not blurred by turbulence in our atmosphere.

How big of a telescope do I need to see Pluto?

Observing Pluto is the ultimate challenge. It is smaller than Earth’s moon and is approximately 3.3 billion miles away from us. You will need a large aperture telescope of at least eleven inches.

Can you see the flag on the moon with telescope?

Yes, the flag is still on the moon, but you can’t see it using a telescope. … The Hubble Space Telescope is only 2.4 meters in diameter – much too small! Resolving the larger lunar rover (which has a length of 3.1 meters) would still require a telescope 75 meters in diameter.

Is a 5 inch telescope good?

5-inch Telescopes offer exceptional resolution for their size. They can resolve double stars at . 91 arcseconds and can be magnified up to 254 times the human eye. 5″ Optical tubes also make exceptional light gatherers by allowing an observer to see 14.3 magnitude stars!

Can you look at Sun through telescope?

Don’t ever look directly at the Sun through a telescope or in any other way, unless you have the proper filters. Or, if you have your own telescope, you will need to obtain a solar filter. … There are even solar telescopes online, which you can access via the web to observe the Sun.

How powerful can a telescope see galaxies?

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 see the stars with a telescope?

Telescopes are wonderful! They let you peer into the vast unknown and see stars, planets, nebula and galaxies far, far away. … Telescopes come in many different sizes. The Moon, Jupiter, Saturn and the Orion Nebula and are terrific to see with smaller telescopes.

How far can a telescope see?

The Hubble Space Telescope can see out to a distance of several billions of light-years. A light-year is the distance that light travels in 1 year.

What can you see with a 90mm telescope?

A 90mm telescope will provide you with a clear view of the Saturn along with its rings, Uranus, Neptune, and Jupiter with its Great Red Spot. You can also expect to see stars with 12 stellar magnitude with a 90mm telescope.

Which telescope lens is stronger 10mm or 20mm?

The larger one is normally between 20mm and 25mm and is the lower power (lowest magnification). The smaller (higher magnification) is normally around 10mm. … A larger image to start with will allow the eyepiece to produce a larger image to view (higher magnification).

What can you see with a 70mm telescope?

The colorful bands and belts of Jupiter, as well as its four major moons, and the rings of Saturn are clearly visible in a 70mm telescope. Mars, Venus and Mercury are visible in a small scope as well, but are extremely reluctant to give up any detail because of their overwhelming brightness.
