I am not sure whether you mean an ordinary optical telescope or a small telescope. You can see a lot through either, and anything you can see in a small telescope can be seen through any other optical telescope. The advantage of a large telescope is often just that it can be used to observe dim nebulae and galaxies.
First off, a warning: NEVER look at the sun with a telescope, unless it is especially set up for the purpose. It will destroy your eyes.
Actually, observing the stars can be fun without a telescope and is a good way to learn about constellations and planets.
You can see some really beautiful things with binoculars. Comets are one good thing, when the are around (you might have to watch the news for this). Also, just looking at a constellation like Coma Berenices, which is not very interesting to the naked eye, can be very memorable. I think it is an astonishingly beautiful, rich field of stars.
A small telescope can give a very nice view of the moon. You do not want to use high power, if you want to see the whole moon, but you can use it to look at craters and so on.
Some of the planets are quite beautiful through a small telescope. Jupiter can be seen at low power, along with four of its moons. If you have access to Sky and Telescope magazine, you will be able to find out when the moons eclipse or occult each other, and this can usually be seen through a small telescope. The rings of Saturn can be seen through a good small telescope, but to get a really nice view, it has to be a good one.
Some small telescopes are especially designed for looking at comets.
Some small telescopes are especially built to look at the Sun. Again NEVER look at the Sun, unless the equipment you have is especially designed for the purpose.
A small telescope can be used to observe some of the galaxies and start clusters. A star cluster sometimes looks rather like a small galaxy, and is quite beautiful. The actual galaxies, however, are much better with bigger instruments. The same is true of nebulae.
One thing you really need to do astronomical observation - and this is by far the most important thing - is to learn about astronomical observation. Learn as much as you can, and the whole thing is much, much more fun. If you can, find a club with experienced observers in it. They do not need to be professional, just experienced.
The most limiting factor in observation is lack of knowledge. The telescope is only secondary.
And, by the way, some things are too big to be seen in a telescope. There is a nebula in the southern sky that is too wide to be seen in a telescope and too dim to be seen by eye. It can be photographed in a camera with a fairly wide angle lens. I don't know, but perhaps a person could see it with a reducing lens (like a magnifying glass, except it makes images smaller).
The most common type of reflecting telescope produces an inverted image. However, it's possible for a reflecting telescope to produce an upright image, depending on exactly how the optics are arranged.
The telescope you are referring to is likely a refracting telescope. In a refracting telescope, light enters through an objective lens which bends the light rays to a focal point where the image is formed. This type of telescope is commonly used in astronomy and for terrestrial viewing.
A telescope that uses one or more mirrors is called a reflecting telescope. Light is collected and focused by the primary mirror, which then reflects it to a secondary mirror that directs it to the eyepiece or detector. This design allows for larger apertures and better image quality compared to refracting telescopes.
Yes, a Hershelian telescope is a type of reflecting telescope in which the primary mirror is tilted so the observer's head does not block the incoming light.
Reflecting telescopes use concave mirrors to gather and focus light to form an image. The primary mirror in a reflecting telescope collects incoming light and reflects it to a secondary mirror, which then directs the light to the eyepiece or camera for viewing. This design is commonly used in telescopes like Newtonian reflectors and Cassegrain telescopes.
the images are clear and can be focused unlike a refracting telescope witch sags under its own weight causing images to be distortedAny telescope forms a real image. Otherwise, it's pretty useless as a telescope.Comments: Refracting telescopes are good these days. They should not sag. Also, Galileo's telescope formed a virtual image, and that wasn't useless.An important point about the image in a reflecting telescope is that it is inverted, as well as being a real image.

A reflecting telescope only uses lenses in the eyepiece. Light is picked up and an image produced by using a concave parabolic mirror.

A refracting telescope is a type of telescope that has a large thin lense at the front and a smaller thicker lense at the end where the eyepiece is. Refracting telescopes use lenses unlike reflecting telescopes that use mirrors to reflect the light. This is a good image of a refracting and reflecting telescope: [See related link]
