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.
What 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.
What can you see with a 400mm telescope?
Answer: One of the farthest away objects you should be able to easily see with this telescope is the Andromeda Galaxy, which is a mere 780 kiloparsecs from Earth. Because this telescope has a shorter focal length (400mm) it is good for low power, wide field views of the sky.
What magnification do you need to see Mars?
Generally, a magnification of 30-50x the aperture (in inches) works well on nights of average-to-good seeing. For example, if you have a 4-inch telescope, try 120x to 200x. If you have an 8″ scope, try 240x to 400x. Again, experiment to get the best view each night.
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.
What can you see with a 60x telescope?
60mm (2.3in) to 70mm (2.8in) aperture or equivalent
With telescopes of this aperture size, you’ll be able to see the moon and her craters, as well as some of the bigger planets.
What can you see with 60x magnification?
Astronomy (entry level)
Whilst you’ll get more magnification out of a telescope, a 60x spotting scope mounted on a tripod is good enough for entry level astronomy and will give a good view of celestial bodies like the moon or jupiter.
How many telescope eyepieces do I need?
Typically, a collection of four – 6mm, 10mm, 15mm and 25mm – will cover most observing requirements. A good selection of eyepieces will serve you well and give you options depending on what you want to observe.
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.
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.
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.
What can you see with a 100mm telescope?
What Can You Expect From 100mm Telescopes? (With Photos)
- 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. …
- The Moon. The Moon looks amazing in these telescopes. …

- Pluto and Dwarf Planets. …
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.
