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

Who improve the telescope?
The telescope was improved by several astronomers and inventors over time. Some key figures include Galileo Galilei, who made significant advancements in telescope design in the 17th century, and Hans Lippershey, who is often credited with inventing the first practical telescope in the early 1600s.
Who uses telescopes?
Many people use a telescope. Astronomers, scientists, astronauts, cosmic data analysts. Even anyone who merely has a curiosity and wishes to know what is beyond our atmosphere uses a telescope.
What are other kinds of telescope used by astronomers to observe star?
Some other types of telescopes used by astronomers to observe stars include radio telescopes, which detect radio waves emitted by stars, and space telescopes like the Hubble Space Telescope, which is specifically designed for observations in space without the distortion caused by Earth's atmosphere. Astronomers also use infrared telescopes to study stars emitting infrared radiation, providing valuable insights into their composition and temperature.
How does a telescope help astronomers see more stars?
A telescope has a larger gathering area (the main lens, or the main mirror) than the human eye. This makes it possible to see the light of fainter objects. Another thing the telescope does is to increase angular resolution. This makes it possible, in some cases, to see two stars that are close together as two stars, whereas the human eye would see them as a single spot of light.
Who uses radio telescopes?
Radio telescopes are used by astronomers to study celestial objects and phenomena in the radio frequency range. They are employed to detect radio waves emitted by objects such as stars, galaxies, and cosmic microwave background radiation. Radio telescopes are also used in radio astronomy research to investigate the structure and composition of the universe.
Who can use the hubble telescope?
Astronomers, mostly those who work for NASA. Some astronomers from Universities can also access it.
Who uses the telescope in their daily life?
Astronomers & some other scientists & enthusiasts.

What are the other use for a telescope?
IT IS USED for us to see planets part of space and some parts of our heavenly bodies and it is also used for astronomers to see heavenly bodies for then to write a fact about our space

How has man been able to learn more about other planets in your solar system?
Astronomers has been going to some of the planets. The advanced telescope can observe the planets more closely. and the satellites has been agthering pictures and datat from the space.
Do astronomers know how to build?
Some astronomers are likely to be good at DIY, but most would probably get a contractor in.
What planet some astronomers don't think is a planet?
Astronomers have decided that Pluto does not meet the definition of a planet.
Limitation of online banking-?
The limitation of the online banking is that it is highly prone to fraud.
What are some of the limitation of statistics?
It is that it cannot be reliable.
