What are the advantages and disadvantages of a ground-based telescope?

What are the advantages and disadvantages of a ground-based telescope?

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 is earth based telescope?

Most telescopes used by astronomers are on Earth. We call these ground-based telescopes. A telescope on the ground has to look through the Earth’s atmosphere to see into space. This is a problem because the atmosphere can blur our images. The air also blocks out light from parts of the electromagnetic spectrum.

What are the advantages and disadvantages of earthen dam?

Advantages & Disadvantages of Earth Dams

• Availability of Earth Materials. Earth is readily available in most parts of the world close to possible dam sites.
• Easy Handling of Earth. Earth can be excavated by hand, transported in baskets and compacted with cattles walking over it.
• Foundation Condition.
• Cost of Construction.

What are the advantages and disadvantages of arch dam?

Advantages of Arch Dam.

• Arch dams are particularly adapted to the gorges where the length is small in proportion to the height.
• For a given height, the section of an arch dam is much lesser than a corresponding gravity dam.
• Because of much less base width, the problems of uplift pressure are minor.

What are the disadvantages of Earth based telescopes?

Disadvantages and limitations of Earth based optical telescopes They can only be used at night. They cannot be used in poor or cloudy weather. They are limited by other atmospheric conditions; particularly convection currents and air turbulence which distort the wave-fronts from the reference object i.e. a star.

Are there any disadvantages to the Hubble Space Telescope?

Although the Hubble Space Telescope is not without its disadvantages, the fact of the matter is that it has been more successful than not. If someone fails to see the need for a space program, someone else could point to the numerous successes of the Hubble Space Telescope.

Which is cheaper a Space Telescope or a ground-based telescope?

Lower Cost. Ground-based telescopes cost about 10 to 20 times less than a comparable space telescope. The costliness of a space telescope such as the Hubble telescope includes the cost of materials, labor and launching it into space. Telescopes on Earth cost less because they don’t need to be launched into space,…

What are three types of Earth based telescopes?

1 Refracting telescopes 2 Reflecting telescopes 3 Cassegrain telescopes
