What does f10 mean telescope? Wide field telescopes have a focal ratio of f/7 or less. Focal ratio also influences the brightness of extended objects like a nebula or galaxy. For example, a telescope with focal ratio of f/5 will show an image of four times the brightness as a telescope with focal ratio of f/10, all other things being equal.
Then, What can I see with a 700mm focal length telescope?

What can I see with 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.
Can you see Saturn with a 70mm telescope?
With a 70mm telescope, you will easily be able to see every planet in the Solar System. … Saturn’s rings might be recognizable under certain conditions, but they will look the same color as the planet. Pluto and the other dwarf planets in the Solar System will most likely be out of reach.
Is a 60mm telescope good?
60mm is enough light gathering power to enjoy a lot of different objects in the sky. … It’s light, easy to use, and enough telescope for many objects in the sky. The thing that holds a lot of these smaller scopes back, especially at the low end of the price range, are poor mounts.
Can I see Neptune with a 70mm telescope?
You can’t compress all those light years of distance with an eyepiece. 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. … Uranus and Neptune are also reachable with small telescopes.

What telescope can see the farthest?
The furthest galaxy ever observed by the Hubble telescope is the GN-z11 galaxy, about 13.4 billion light-years away. As the galaxy is so far away and light can only travel so fast (299,792,458 meters a second), Hubble is effectively looking back in time when viewing very distant objects.
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.
How much zoom do you need to see Mars?
In general, the best magnification for viewing Mars is 35x per inch of aperture when using a telescope of up to about 7″, and roughly 25x to 30x per inch of aperture for larger telescopes.
Are 50mm telescopes good?
50mm (2 in) telescopes are the most basic, entry-level, budget telescopes on the market. They are mostly targeted at kids and some of them could even fall into the toy category. We generally don’t recommend 50mm telescopes unless you are on a very tight budget or you are looking for a gift for a 5-year-old.
How do I choose a telescope?
The main specification you want to consider when choosing a telescope is its aperture—the diameter of its main mirror or lens. The larger the diameter, the more light the telescope collects, allowing you to see fainter objects and more detail on nearby, bright objects like the Moon.
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.
What can I 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 60mm refractor telescope?
This compact 60mm offers enough light gathering ability to view Jupiter, Saturn, the Orion Nebula, craters on the Moon, and more. Plus, with the Zhumell 60mm AZ Refractor Telescope, you’ll always be ready to view passing comets and other celestial events like the “”Blood Moon.
What can you see with 80 mm telescope?
For moon and sun, double stars, deep sky within reach, and casual looks at planets (especially Saturn) an 80mm can do well. The 1.5 arc-second resolution of 80mm scope is respectable, and the doubling of light grasp compared to 60mm is obvious.
Which is better 60mm or 70mm telescope?
Standard 1.25′ diameter eyepieces are large enough to provide a very good working field of view. They are commonly provided on many intermediate and advanced level telescopes.
…

| Aperture Diameter | Light Gathering Ability |
|---|---|
| 60 mm | 70 times the unaided human eye |
| 70 mm | 100 times the unaided human eye |
What size telescope do I need to see planets?
Telescopes that have 4 or 5 inch diameters are great for viewing solar system objects like the planets, our Moon, and Jupiter’s moons.
