What are the advantages and disadvantages of ground-based telescopes?

Compared to space-based telescopes, ground-based telescopes have much to offer. They can be built bigger and for less money. They’re easier to maintain and upgrade. Practically speaking, they also have a much lower risk of being damaged by one of the 500,000 pieces of debris flying through the cosmos—or space junk.

What are the advantages and disadvantages of a telescope?

Advantages and Disadvantages of an Astronomical Telescope

• It creates large magnification,
• Superior resolving power per inch of aperture,
• Its field of view is wide,
• Superior performance in inferior conditions – image steadier,
• The image is free from aberration, not reflections or interruption of the light path,

What are problems with ground-based telescopes?

In addition, turbulent motion in the atmosphere blurs the light travelling through it, causing objects to twinkle and appear fuzzy. Another problem with ground-based telescopes is that they are subject to local weather conditions, and high clouds can ruin the chance of making any useful observations.

How far away from Earth will the Webb telescope be placed?

1.5 million kilometers
Webb Orbit Webb will orbit the sun 1.5 million kilometers (1 million miles) away from the Earth at what is called the second Lagrange point or L2.

What is the biggest disadvantage of putting a telescope in space?

Which of the following is the biggest disadvantage of putting a telescope in space? Space telescopes are much more expensive than similar ground-based telescopes.

What are the advantages and disadvantages of telescopes?

They can be heavy, especially larger aperture telescopes, because of their need for large lenses. They can also have a longer body which may impact on transportation and storage. They may also be more expensive, as large high quality lenses are more costly to produce. Cheaper lenses are more susceptible to aberrations.

Can a space telescope be serviced by a ground based telescope?

Other space telescopes cannot be serviced this way. But as technology advances, both telescopes on the ground and in space are continuing to improve. Newer, more advanced ground-based telescopes implement adaptive optics, a technique to sharpen blurry images right as they’re being taken.

Are there any telescopes that can be repaired in space?

Nevertheless, space-based telescopes are expensive to build and difficult to maintain. NASA’s Hubble, with infrared eyes built by the University of Arizona, is the first space telescope designed to be repaired by astronauts in space. Other space telescopes cannot be serviced this way.

What are the advantages and disadvantages of optics?

The optics provide the advantages of both lenses and mirrors, so they make a great all purpose telescope. They may suffer a slight loss of light because of the positioning of the secondary mirror. Also catadioptrics may suffer from image shift, or a jump in focus, due to the primary mirror being moved when focusing.
