What were some of the limitation of telescope that astronomers encountered?

Answer 1

Several things limit which celestial objects can be seen with a telescope on Earth.

- The apparent magnitude of the object.

- The telescope you are using, tracking system and camera capability.

- Weather conditions, atmospheric and light pollution affecting airglow.

- The elevation of the object: lower in the sky means a thicker slice of atmosphere to interfere, more limitation.

- Your elevation relative to sea level: lower elevation means a thicker slice of atmosphere to interfere, more limitation.

- Red Shift - the object you are observing is moving away so fast that the color of the light reaching us has dropped into the infrared range, invisible to the human eye.

Generally, the faintest objects observable in visible light with 8m ground-based telescope is about 27.

Answer 2

If the telescope were placed in space (like hubble) the images would be greatly improved due to the lack of both atmosphere and ambient light, such as streetlights. The lack of atmosphere means that the light from distant objects need not travel through turbulent gases found in the atmosphere. this would eliminate the 'twinkling' of stars, and the lack of ambient light would result in much greater detail in the image.

Answer 3

Basically the cost. Telescopes with mirrors that have 8 meters in diameter are being built, several such telescopes are combined into larger telescopes; and larger mirrors are planned - but all this has a huge cost.

Answer 4

What limits the size and magnification of a refracting telescope is by the objective lens

Answer 5

The atmosphere scatters the light, so the images aren't very clear, but once we get outside of the atmosphere, like with the hubble telescope, the images are perfectly clear

Answer 6

there are a lot of power,too

much infact.

Answer 7

The lenses
