Yes, you can use a normal telescope to see some planets under certain conditions. For example, you can easily view bright planets like Venus and Jupiter with a basic telescope. However, to see the faint planets in our Solar System such as Uranus, Neptune, and Pluto, you will need a telescope with more sophisticated technology.
Telescopes with larger apertures and higher magnifying power are best for viewing these planets since they will provide the clearest image. Depending on the telescope you have, you may also need to use different eyepieces in order to see the planets more clearly.
Additionally, when trying to observe planets, make sure you look up when and where the planet is visible from viewing from your location and make sure to find the darkest sky possible. This will ensure you have the best chance of seeing the planet clearly with your telescope.
What can you see with a cheap telescope?
With a cheap telescope, you can see a variety of things in the night sky, such as the Moon and the rings of Saturn; distant stars like the Hercules Cluster and the wonders of deep space like the Andromeda Galaxy.
You can also observe some of the planets in our Solar System such as Venus and Jupiter and their moons, and observe comets as they pass by Earth. Some people have also had luck observing more distant celestial phenomena like nebulae, supernova remnants, and even galaxies.
Telescopes with greater power, however, will be able to provide a much greater view of distant celestial objects. Furthermore, with great care and patience, the features of the Moon, the phases of Venus, the Four Galilean moons of Jupiter, and the stars and nebulae of the Milky Way can be explored in more detail.
Can beginner telescopes see planets?
Yes, beginner telescopes can see planets, but they may be difficult to find. Even the most basic telescopes, such as those sold in department stores, can reveal the four bright planets found in our own solar system.
While the majority of astronomers use much more powerful telescopes to study planets in greater detail, even a basic telescope can allow for a great viewing experience of Saturn, Jupiter, Venus, and Mars.
To see the planets, you should have a clear view of the night sky and may have to wait for a night when the atmosphere is especially stable to get the clearest look. You may also need to adjust the magnification and focus settings to bring the planets into view.
What does Mercury look like through a telescope?
When viewed through a telescope, Mercury looks like a small, round planetary disk with various layers of gray and light gray hues. Its most distinguishing feature is its craters. Through an 8- to 10-inch telescope, it is possible to observe up to 15 of these craters, although some of the fainter ones may require more powerful instruments.
Additionally, a few of the dark patches visible on the planet’s surface could be sunglasses that are related to Mercury’s past volcanic activity. When observed up close, Mercury also has a quite interesting twilight area that appears to sit just outside of the disc.
When viewed from the Earth using more advanced telescopic technology, the twilight area is seen to actually consist of several shallow basins.
What magnification telescope do I need to see planets?
The magnification needed to observe planets through a telescope depends on the size of the telescope and the planet you’re trying to observe. Generally, a beginner telescope with an aperture of at least 4 inches and a magnification of 40x is sufficient to observe planets.
With larger aperture telescopes, such as those 8 inches and greater, maximum useful magnification can exceed 230x. However, because of atmospheric interference, the actual magnification you’ll get with a higher magnification is usually less.
For instance, with an 8-inch telescope, actual magnification of planets may be around 100x to 150x. Once you’ve determined the magnification you’d like to use, the next step is to match the eyepiece to your telescope.
A 25 mm eyepiece is usually used to view the moon and planets in most telescope sizes, but different sizes of eyepieces may be better suited for the type of target you plan to observe. If you plan to observe planets, it’s best to choose an eyepiece with an expansive field of view to take in the planet’s entirety.
Which eyepiece is for viewing planets?
When it comes to viewing planets, most astronomers recommend using a planetary eyepiece that has low power and a wide apparent field of view. A low power eyepiece will provide a larger image of the planet, which allows for more detailed viewing.
The wide field of view will give the observer a wider view of the sky and more area to view the planet and its satellites. Generally, low power eyepieces with a field of view between 40 to 60 degrees are best suited for viewing planets.
Some common eyepieces to use for viewing planets include Plössl, Kellner, Orthoscopic, and Super Wide Angle eyepieces. Although Plössls are the most common choice, Super Wide Angle ones can provide an even wider view of the sky, allowing for the observer to take in more of the planets and their satellites.
Additionally, it is important to note that the magnification power of an eyepiece should not exceed that of the telescope to get the best image possible.
How do I choose a telescope?
Choosing the right telescope for your needs can seem daunting at first. First, consider whether you want a refracting or reflecting telescope. Refracting telescopes use lenses and are better suited for viewing distant objects such as the planets, and reflecting telescopes use mirrors and are better for viewing galaxies, star clusters, and nebulae.
Second, consider the aperture size (measured in mm) of the telescope. Aperture size refers to the diameter of the telescope’s lens or mirror which determines how much light can be gathered and therefore how much detail can be seen in the night sky.
Generally, larger aperture sizes are better as they are able to capture and project more detail. Third, consider the focal length (measured in mm) of the telescope. This is the distance between the primary mirror or lens, and the point of focus.
Shorter focal lengths are better for wide-field views, while longer ones are better for higher-magnification images, but the tradeoff is usually a reduced field of view. Finally, decide on a budget. Telescopes have a huge range of prices and features so you’ll want to decide on how much you’re willing to spend.

What size telescope do I need to see the rings of Saturn?
The size of telescope you need to see the rings of Saturn depends on the visibility conditions and your location. If you are in an area of the world with clear night skies, a 6 to 8 inch (150 to 200 mm) telescope is recommended for viewing the rings of Saturn.
A telescope of this size should provide a good level of magnification and allow you to see the distinctive shape and structure of the ring system. If you have access to a larger telescope, such as an 8 to 12 inch (200 to 300 mm) instrument, you will be able to see more detail in the rings, such as distinct divisions in the broad structure of the planets rings.
For the best and most detailed views of the rings of Saturn, however, a large reflecting telescope of 14 inch (350 mm) or more is advised. Such a telescope should provide excellent magnification and allow you to observe Saturn’s rings in the finest detail.
Is a 100x telescope good?
A 100x telescope can be a good tool for recreational astronomy depending on your individual goals and circumstances. On one hand, it offers a powerful magnification, which can help you see celestial objects from further away than a lower magnification telescope would allow.
However, to get the highest level of quality from your telescope, it is important to consider other factors. For example, the aperture of the telescope (the diameter of the objective lens) is a bigger factor in determining image quality than magnification.
Additionally, since the magnification of a 100x telescope can make objects more difficult to spot and keep in the field of view, its best to opt for a slightly lower magnification if you’re planning to observe objects like planets and galaxies.
The resolving power (the level of detail) of a 100x telescope can also be hampered by atmospheric conditions, so its important to keep an eye on the weather before going out to use it.
What can a 70mm telescope see?
A 70mm telescope is great for viewing both celestial bodies in the night sky and ground-based objects. In terms of celestial bodies, you can expect to see the Moon in great detail, along with planets like Saturn, Jupiter and Mars, and some of the brighter stars, clusters and nebulae.
With a 70mm telescope, you’ll be able to get a nice look at the major components of our Solar System such as its planets, moons, asteroids and comets. It is also powerful enough to show some galaxies and star clusters.
Ground-based objects for viewing can include items such as mountain ranges, valleys, hills, cityscapes, lakes, rivers and trees. When viewing during the day, you can see objects like boats, bridges and tall structures.
It is not a great telescope for watching wildlife such as small birds, but you can look for animals on wide grassy areas or in other open spaces.
In general, a 70mm telescope is a great choice for beginners to astronomy because it provides great views of the night sky. It is also capable of providing good views of many ground-based objects when used during the day.
