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
there are a lot of power,too

The lenses
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.
Each lens absorbs some light, making the telescope weaker. I suppose each lens could also introduce certain abberations.
Invented during the course of the 17th century and still undergoing new improvements and revisions, the telescope is one of the most remarkable and helpful inventions yet devised. In just its astronomical usages, the telescope has enlarged humankind's understand of the world in a revolutionary way. It may safely be said that, without the telescope, there would have been no modern age: humanity would still be unaware of the real nature of life outside of Earth.
Astronomers label the stars within constellations according to apparent magnitude.
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.
Astronomers, mostly those who work for NASA. Some astronomers from Universities can also access it.

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

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.

Some astronomers are likely to be good at DIY, but most would probably get a contractor in.
Astronomers have decided that Pluto does not meet the definition of a planet.
