How much zoom does a telescope have? It’s equal to the telescope’s focal length divided by the eyepiece’s focal length. As a rule of thumb, a telescope’s maximum useful magnification is 50 times its aperture in inches (or twice its aperture in millimeters). True Field of View: The circle of sky that you see when you look through a telescope or binoculars.
Then, What is the difference between a telescope and a camera lens?
The only difference I can see is that a camera lens projects a real image on a surface, whereas a refracting telescope projects a virtual image, but other than that I don’t understand. :confused: Using film since before it was hip.
Secondly, What can you see with a 100mm telescope? What Can You Expect From 100mm Telescopes? (With Photos)

- The Moon. The Moon looks amazing in these telescopes. …
- Mars. …

How powerful does a telescope have to be to see the rings of 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.
How powerful 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.
Is a lens or a telescope better for astrophotography?
Everything being equal, a telescope has an advantage over a camera lens for astrophotography because 1) a telescope allows you to place a guidescope on top of it, which is essential for exposures over 1 minute long and 2) a telescope allows you to put a filter or a filter wheel in the optical path much more easily.
Is a Schmidt Cassegrain good for astrophotography?
Schmidt Cassegrains are high-level all-purpose telescopes, ideal for viewing the moon, planets, and deep-sky objects. They are also ideal for astrophotography, using everyday DSLR cameras.
What can you see with a 130mm telescope?
You will be able to see Moon, Jupiter, Mercury(looks like a star), Venus, Saturn pretty well. Mars would be disappointing a bit. Its too small. You will get 65x with a 10 mm.
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.
Can I see galaxy with telescope?
Galaxies are some of the most distant objects we can observe. While most planets, stars, and nebulae are usually pretty nearby to us, we can observe galaxies that are millions of light-years away. … Even if a galaxy is bright, the most you might typically see is its core with a 4-inch telescope.
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.
How much does a real telescope cost?

How big of a telescope do I need to see Pluto?
For the best chance of seeing it, you need very dark skies, a good telescope, a star chart, and abundant patience. If you’ve done this before, and have all of the above, then it’s possible to spy Pluto with a 5” telescope. Realistically, you’ll need at least an 8” scope is the best bet to go Pluto-hunting.
Can a telescope see the flag on the moon?
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.
Can you see Pluto with a telescope?
Yes, you can see Pluto but you’ll need a large aperture telescope! Pluto resides at the very edges of our solar system and shines only at a faint magnitude of 14.4. … The dwarf planet is 3,670 million miles away from the Sun and looks just like another faint star in your telescope.
Can you look at stars through 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.
What does an equatorial mount do?
An equatorial mount is a mount for instruments that compensates for Earth’s rotation by having one rotational axis parallel to the Earth’s axis of rotation. This type of mount is used for astronomical telescopes and cameras.
Why are refractors better for planets?
The relatively small aperture of a refractor therefore often has an advantage over a larger reflector-type scope for this kind of observing, as there is less glare from a larger scope’s brightly lit planetary surfaces to wash out faint detail.
What does APO mean in telescopes?
An apochromat, or apochromatic lens (apo), is a photographic or other lens that has better correction of chromatic and spherical aberration than the much more common achromat lenses.
Who is Astro biscuit?
Astrobiscuit is a YouTube channel created and maintained by Rory, an amateur astrophotographer from London. … From shooting Jupiter, Saturn and Mars for a £100 budget to putting a £600 astrophotography rig up against a £6000 rig, Rory does not cease to entertain us.
How much magnification do you need to see Saturn’s 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 aperture for a telescope?
As a rule of thumb, your telescope should have at least 2.8 inches (70 mm) aperture — and preferably more. Dobsonian telescopes, which are reflectors with a simple mount, provide lots of aperture at relatively low cost. A larger aperture lets you see fainter objects and finer detail than a smaller one can.
What can you see through a 90mm telescope?
c) Deep Sky Objects: dozens of globular clusters, emission nebulas, planetary nebulas, and galaxies. Also, all of the Messier objects, although most galaxies will remain relatively featureless hazy patches. This is an example of Mars as seen through a telescope with a 90mm aperture.
How much magnification do you need to see Jupiter?
To look at planets like Jupiter and Saturn, you will need a magnification of about 180; with that you should be able to see the planets and their moons. If you want to look at the planet alone with higher resolution, you will need a magnification of about 380.
