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.
What is the best 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 telescope magnification is good?
Another rule of thumb… the maximum useful magnification of a telescope is
about 50x the aperture in inches
. Any higher and the image gets too dim and fuzzy to be useful. So a 4-inch scope can get you about 200x before the image gets too fuzzy and dim, a 6-inch scope gets you 300x, and so on.
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).
What magnification is most useful?
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).
What can you see with a 25mm telescope?
25mm – 30.9mm Telescope Eyepieces: These are extended field eyepieces for longer focal length – good for
large nebula and open clusters
. For shorter focal length, they are fantastic for large objects such as the Orion nebula, views of the full lunar disc, large open clusters and more.
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).
How big of a telescope do I need to see the rings of Saturn?
Viewing Saturn’s Rings
The rings of Saturn should be visible in even the
smallest telescope at 25x
. A good 3-inch scope at 50x can show them as a separate structure detached on all sides from the ball of the planet.
How big of a telescope do you need to see Neptune?
To catch a glimpse of Neptune, you’ll need a telescope of
at least eight inches of aperture at about 100x to 150x magnification
. With equipment like this, you’ll still need steady skies to observe this tiny bluish disc. As with Uranus, do not expect to see any surface features or its faint rings.
How good is a 90x telescope?
Thus a 90x magification on a very large (wide) telescope would let you see
a very large number of
things (if you are in an area where the sky is dark), but 90x on a small telescope would let you see a number of interesting things (the Moon, planets, some nebulae and star clusters) but not relatively faint objects.
What magnification is needed for deep sky?
In practice, the optimum magnification for most objects is somewhere
between about 8× and 40× per inch of aperture
— toward the low end for most deep-sky objects (star clusters, nebulae, and galaxies) and the high end for the Moon and planets.
What can you see with a 40mm telescope?
Apart from these objects 40mm will show
phases of venus and many details on the moon like craters, mountains and maria
. Orion nebula and Andromeda galaxy will be easy objects for 40mm scope. Again one can see many stars in Pleiades and many other star clusters.
Is a 20mm telescope good?
A 20 mm
is useful
just as a 13 mm is useful in most any telescope but I’m not sure “all purpose” is a good description. My telescopes range in focal length from under 400 mm to about 2800mm, a 20mm is not a planetary or high power or even mid-power eyepiece in any of them, it’s a low to mid power deep sky eyepiece.
What can you see with a 50mm telescope?
This attractive and solidly constructed entry level telescope will let you see a great amount of detail on the Moon, view the
main division in the rings of Saturn
, the separation of the cloud belts of Jupiter as well as its primary moons, and observe countless star clusters, double stars, nebulae and more.
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.
What can you see with a 76mm telescope?
Lots to be seen with 76mm of aperture!
Craters on the Moon
, Jupiter’s 4 main moons and maybe the main cloud belts, Saturn’s ring, quite a few of the brighter galaxies and nebula if the skies are dark enough from your location. If you are a beginner some of these things will require a little effort to find.
What is the difference between 10mm and 20mm telescope lens?
Magnification is determined simply by dividing the focal length of the telescope by the focal length of the eyepiece. This means that a smaller number on an eyepiece gives a higher magnification.
A 10mm eyepiece would provide twice as much magnification as a 20mm eyepiece
.
Can you see Mars with a telescope?
Any telescope will work for Mars
, but the bigger, the better. A 4-inch refractor or a 6-inch reflector are the recommended minimum. Apply high power (175× or more), and wait for a night with steady seeing, when the Martian disc is not blurred by turbulence in our atmosphere.

Now what will you see in a good 80mm? First Planets: all the planets and
some asteroids
. Mercury like a point, Venus with the phases, on Jupiter the cloud bands and 4 satellites, maybe not the Great red spot, on Saturn the rings and Cassini division, Uranus and Neptune like blue-green dots.
What can I see with an 11 inch telescope?
11-inch Telescopes offer exceptional resolution for their size. They
can resolve double stars
at . 42 arcseconds and can be magnified up to 304 times the human eye. 11′′ Optical tubes also make exceptional light gatherers by allowing an observer to see 16 magnitude stars!
Can Uranus be seen with a telescope?
“Although Uranus is not considered a visible planet, at opposition it is bright enough to be visible for someone with excellent eyesight under very dark skies and ideal conditions,” NASA said in a statement. “If you know where to look, it should be visible with binoculars or
a backyard telescope
.”
Can you see a galaxy with a 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.
