A telescope as actually a light bucket. It collects light from the objects in space using either a lens, or more usually a mirror.A main mirror reflects the light to a smaller one,which begins the light to a focus where an image of the object is formed
You could make the telescope able to see better in the dark and make it more portable.
With a suitably giant telescope, probably yes.
There are usually 3 adjusting screws on the front of the telescope over the secondary mirror. You point the telescope at a bright star and then defocus it this forms a donut-like image in the telescope. If you center the "doughnut" in the middle of the telescope view you will see that the "doughnut" has the dark area in the middle off center (If the scope is not colminated properly). What you want to do is move the doughnut to the edge of the telescope in the direction where the dark center is "out of center". Now you will tighten one of the three screws in the front. The way to figure out which screw to adjust is by placing your finger in front of the scope where the doughnut is out of center. You will see a dark line in the doughnut image where your finger is and it will actually be pointing to one of the three screws in front - that screw needs to be tightened. You repeat these steps until when you put the dougnut in the center view of the telescope and see a perfect looking "doughnut" with the dark part centered perfectly.
get a telescope, wait until it is dark and stargaze for a while and you might see one
Definitely, a 500-mm (20-inch) telescope is a large instrument because 500 mm is the diameter of the main mirror or lens, so the telescope would be 3-5 metres long. A telescope this size could see faint stars down to a magnitude of round about 15. Remember that you don't need any telescope at all to see stars. On a clear night in a dark place, you can see a few thousand of them with only your eyes.
Without a telescope, you can see the different phases of the moon, lunar craters, and dark patches known as lunar seas or maria. You may also see some of the moon's prominent features, such as the Tycho crater or the Apennine Mountains.
On the surface of the moon, you can see various features such as craters, mountains, plains, and dark areas known as maria. These features are visible to the naked eye, without the need for a telescope.
Uranus is barely visible to the naked eye on very dark nights, to those with good eye sight. Neptune requires a telescope to see.
You could see Neptune from Earth with a telescope if you knew exactly where to look.
Yes it is. Everything you can see without a telescope (nd most of what you can see with a small telescope) is within the Milky Way galaxy with the notable exception of the Andromeda galaxy which you can see with the unaided eye. (But it should be pretty dark to be able to see it).
Yes, a dark spot has been observed on Uranus. It was first observed in 2006 by both the Hubble Telescope and the Keck Telescope.
Yes, and without a telescope. But with a telescope, you can easily make it out seeing a blue ball about the size of the Esc key on a laptop.
