What is the purpose of a Dobsonian telescope?
The Dobsonian telescope was designed with a large objective diameter to observe very faint deep sky objects. It was originally designed from readily available components to provide a large yet still portable low-cost option for telescope users.
Why do stars appear as faint curved lines on a telescope?
On a good telescope they will not. Otherwise it is probably due to the inferior quality of the lenses.
Can asteroids be observed by a telescope?
Yes, you need a telescope or powerful binoculars, because the asteroids are too faint to see with the naked eye.
How big does neptune look from earth?
With the naked eye - invisible. With a telescope - a faint dot.
Is Uranus the last planet you can see without a telescope?
Yes it is.Uranus can be seen without a telescope but it will be very faint and you have to have near perfect conditions and no light pollution.
Telescopes cannot detect?
Telescopes can not detect any radiation for which they were not specifically built. For example, a radio telescope is specifically designed to detect radio waves. Also, telescopes can not detect radiation that is too faint for them. What is too faint depends on the capabilities of the telescope.
What is a telescope that uses a mirror to collect light emitted by distant or faint objects?
This type of telescope is often referred to as a Schmidt-Cassegrain telescope, and can be short and wide. They have an eyepiece that extends at a right angle from the body, and have a disk in the middle of the lens, behind which is the mirror.
What is a slanted view in science?
In the Atacama Desert of northern Chile, a microwave telescope has taken the best snapshot of an exquisitely faint echo of the big bang.
How is Pluto difficult to find?
Pluto is difficult to observe from Earth because it is about 3.66 billion miles away, and only appears as a faint point of light.
What is meant by collecting area. How does it affect the ability to see faint objects?
Collecting area is the area over which a telescope focuses and collects light from a particular object. Generally this is the size of the opening of the telescope. The greater the collecting area, the more photons per second the telescope can collect from the area of interest. Having more collecting area reduces the amount of time for any exposure to be made. For really faint objects having more collecting area can bring the object above the observing threshold of the equipment you have, making it possible to detect it.
When is the best time to view Uranus and where in the sky would you look?
You need to get an emphemeris, or a listing of planetary positions and find out which constellation Uranus is in, then find out when that constellation is in the night sky. Uranus is quite faint, but you can see it without a telescope if you have good conditions and good eyes. The darker the sky, the better.
Can a 500mm telescope see stars?
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.
