Is a 900mm telescope good?

In addition to a great planetary telescope, you’ll want some short focal length, high-magnification eyepieces. … The focal length of the telescope is 900mm, so to achieve the maximum useful magnification, then a 4.5mm eyepiece would be ideal.

What is a good magnification for a telescope?

For most purposes, a telescope’s maximum useful magnification is 50 times its aperture in inches (or twice its aperture in millimeters) . So you’d need a 12-inch-wide scope to get a decent image at 600×. And even then, you’d need to wait for a night when the observing conditions are perfect.

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 type of telescope is best for viewing planets?

How far can you see with a 80mm telescope?

With an 80mm f/6 a 40mm 68° eyepiece gives a 12x view over 5.5 degrees across – a rock steady tripod mounted view like a big binocular might see. An 80mm f/10 or f/11 won’t go quite as wide but can still show something close to 2 to 3 degrees at low power of about 25x, depending on focuser size.

What can you see with a 500mm telescope?

A 500mm telescope will yield a lunar image that’s about 5mm across in a DSLR camera with a full-frame, 35mm-format sensor; a 1,500mm telescope will produce a 14mm image, and a 2,000mm telescope results in an 18mm image.

Is a 70mm telescope good?

With a 70mm telescope, you will easily be able to see every planet in the Solar System. You will also be able to take a great look at the Moon and clearly distinguish most of its recognizable features and craters. Mars will look great. … The magnitude limit of a 70mm telescope is about 11.9.

Is a 700mm telescope good?

Yes indeed, a 60mm refractor with a 700mm focal length is most definitely ‘good enough’! Chances are pretty good that the optical quality of your telescope lies somewhere within the good to excellent range! Some of us (myself for one) started out with a telescope of similar size.

Is a 90mm refractor good?

The Orion Astroview 90mm refractor is an ideal telescope for novice astronomers ready to invest in their first model. There are some shortcomings, but this affordable telescope offers the laser-sharp optics that refractors are known for and is ideal for your first views of the Moon, planets, and stars.

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

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. Want to see Saturn’s rings? First, you need to find Saturn in the sky.

How big 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.

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.

Is an 80mm telescope good?

80MM Large Aperture Telescope is a perfect telescope for adults and kids to use together with bright image quality and high magnification power. Very suitable for beginners to explore the vast sky, like the moon, the planet, star clusters and fog and so on.

Is a 80mm refractor telescope good?

80mm Refractor. The iOptron® 80mm refractor (R80) is a fantastic astronomy telescope that is portable enough to take anywhere. … You’ll see spectacular star clusters, wispy nebulas, and expansive galaxies with this telescope, but it also excels at viewing objects in our solar system.
