What is the best way to aim a telescope towards a star?
- Suppose we point a telescope positioned here at a star and then move the telescope about one of these axes, the one indicated by the RA shaft, to keep track of the star all night. A seemingly complicated arrangement can actually be made simpler by requiring only movement along one axis.

How do I know where to aim my telescope?
He is the Finder. A finderscope is usually affixed to the side of a telescope to assist the user in aiming the instrument. It is necessary to use a finder because the primary telescope has such a small field of view — that is, it only displays a small portion of the sky — that it is impossible to identify where it is aimed just by looking.
Why can’t I see anything from my telescope?
If you are having difficulty locating things via your telescope, check that the finderscope is properly aligned with the telescope. This little scope is mounted to the rear of the telescope, right above the eyepiece holder, and is known as the finderscope. This is best accomplished during the initial setup of the scope.
How do you read a telescope power?
The formula is straightforward: divide the focal length of the scope by the focal length of the eyepiece. As an example, if you have a scope with a 1,200mm focal length and an eyepiece with a 20mm focal length, your magnification would be 60 times. Any telescope’s magnification is proportional to the focal length of the eyepiece used; the narrower the focal length, the greater the magnification.
What is a good telescope to see planets?
The most effective telescope for seeing planets

Can a telescope see the flag on the moon?
Is it possible to view an American flag on the moon if you use a telescope? Even the powerful Hubble Space Telescope is unable to acquire images of the flags on the moon due to their distance from the Earth. However, the Lunar Reconnaissance Orbiter, an unmanned spacecraft that was launched in 2009 and is equipped with cameras to take photographs of the moon’s surface, is a good alternative.
Which eyepiece is best for viewing the moon?
A 13mm or 14mm eyepiece would suffice for a medium power eyepiece (about 150X magnification). An eyepiece between 25mm and 30mm in diameter would be suitable for a low power eyepiece (about 75X), which is excellent for finding and centering or seeing very huge and near objects such as the Moon or the Sun.
Can you look at Sun through telescope?
If you don’t have the correct filters, you should never stare directly at the Sun using a telescope or any other means. You will also require a sun filter if you have your own telescope, which you can purchase separately. There are even solar telescopes available online, which you may use to see the Sun from the comfort of your own home.
Why do you have to polar align a telescope?
An important first step in preparing for a night of visual observation or astrophotography is to align the stars on the horizon. What is the significance of this? It is possible to track objects in space with pinpoint accuracy by adjusting the axis of your telescope mount to align it with the motion of the sky. For owners of German equatorial mounts (GEMs), the procedure is rather straightforward.
