To get less than 2-meter (6-foot)resolution when the Moon is closest, we’d need a telescope able to resolve angles as small as 0.001 arcsecond. That translates into a diameter exceeding 100 meters (4,000 inches).
What size telescope do you need to see the craters on the moon?
What is the best magnification to use on the moon? Try all of them; they’re all good. A low magnification of around 50x will show you the whole moon and give you the “big picture.” But to see the moon at its best, try a high magnification, at least 150x.
Can you see a man on the moon with a telescope?
The landers, rovers, and other junk left on the lunar surface by the astronauts are totally invisible. Using a bigger telescope won’t help much. You’d need a mirror 50 times bigger than Hubble’s to see the landers at all, and we don’t have a 100 meter telescope handy.
What can you see with a 100 telescope?
There are tons of amazing, fantastic and beautiful things you can observe in a telescope.
- The Moon. The Moon is the Earth’s only satellite and a wonderful object for observation. …
- The Sun. …

How far can optical telescopes 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 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.
What can I see with a 40x telescope?
At 40x you can use the scope for several astro viewing aspects: Clusters, Open and Globular, double stars, some nebula – M42 being the obvious. Depending on how dark your skies are some planetary nebula. And as ever in this hobby there is the moon.
Can you see the US flag on the moon?
Yes, the flag is still on the moon, but you can’t see it using a telescope. I found some statistics on the size of lunar equipment in a Press Kit for the Apollo 16 mission. The flag is 125 cm (4 feet) long, and you would need an optical wavelength telescope around 200 meters (~650 feet) in diameter to see it.
Can you still see the flag 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.
Why can’t we zoom in on the moon?
It’s focal length is too long. The focal length of a lens is that distance where light is focused on the eye looking through it and the object it’s aimed at. You need a telescope to view the moon clearly. The focal length is 200k+ miles.
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.
What can I see with a 100mm refractor telescope?
Any object with a magnitude below the telescope’s max magnitude should be visible.
- The maximum magnitude of a 100mm telescope is 13.6. For reference, the Moon has a magnitude of -12.74 and Mars has a magnitude of -2.6. …

What can you see with a 150mm telescope?
150-180 mm refractors, 175-200 mm reflectors and catadioptric telescopes:
- binary stars with angular separation of less than 1″, faint stars (up to 14 stellar magnitude);
- lunar features (2 km in diameter);
- Clouds and dust storms on Mars;
- 6-7 moons of Saturn, planetary disk of Titan may be observed;
How Far Will James Webb see?
How far back will Webb see? Webb will be able to see what the universe looked like around a quarter of a billion years (possibly back to 100 million years) after the Big Bang, when the first stars and galaxies started to form.
How far will the James Webb telescope be from Earth?
The most powerful space telescope ever launched just fired its thrusters to reach its permanent cosmic address. With this final course adjustment complete, the James Webb Space Telescope (JWST) is now orbiting around the sun at a distance of nearly 1 million miles (1.5 million kilometers) from Earth.
What telescope can see the farthest?
The Hubble Space Telescope has captured the farthest-ever view into the universe, a photo that reveals thousands of galaxies billions of light-years away. The picture, called eXtreme Deep Field, or XDF, combines 10 years of Hubble telescope views of one patch of sky.
