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.
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 magnification do you need to see 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 is a good magnification on 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 100x magnification telescope?
100x – This is a great all around view of Jupiter, as you can see cloud detail on the planet, and see all four moons all in the same FOV. The Great Red Spot can also start being seen as well as a tiny orange colored dot on the planet (if it’s on the side facing Earth).
How good is a 70mm telescope?
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.
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.
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).
Is 10×50 binoculars good for astronomy?
Ask any seasoned astronomer which is the best binocular magnification for getting started in skywatching and the answer will be 10×50. … What’s more, the lower magnification offers a wider field of view over 10x50s.
What size telescope do you need to see Uranus?
You need at least an 8-inch objective to stand any chance of seeing Uranus’ brightest moons. In this context, ‘brightness’ is relative because Uranian moons are small and dark. The brightest two are called Oberon, which shines at magnitude 14.1, and Ariel, which is magnitude 14.4.
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 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.
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.
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 you see with a 130mm telescope?
With a 130mm (5. 1″) aperture size, the Polaris 130 will deliver bright, clear images for the aspiring astronomer to enjoy. Whether you’re viewing the Moon, planets, or deep-sky objects such as nebulae, galaxies, and star clusters, the view through the Polaris 130 will keep you looking up for a long time.
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.
