What is the longest range telescope?

the Hubble Telescope
How far can the Hubble Telescope see? The furthest galaxy ever observed by the Hubble telescope is the GN-z11 galaxy, about 13.4 billion light-years away.

What can you see with a 102mm telescope?

This large 102mm (4.0″) aperture gives bright, sharp images for both land and celestial objects. Whether you’re viewing the rings of Saturn, the moons around Jupiter, nebulae, or land objects, the Infinity 102 Refractor allows the first-time observer to explore the world, solar system, and beyond.

How far will the James Webb telescope be from Earth?

about 1 million miles
The telescope will journey to an isolated spot about 1 million miles (1.6 million kilometers) from Earth known as a Lagrange point, a gravitationally stable spot between two celestial bodies.

What can I see with 130mm telescope?

You will be able to see Moon, Jupiter, Mercury(looks like a star), Venus, Saturn pretty well. Mars would be disappointing a bit. Its too small. You will get 65x with a 10 mm.

How many stars can you see with a 250mm telescope?

Under truly dark skies – where the milky way is bright, highly structured and you can barely resolve the constellations due to the sheer number of stars – a large 250mm telescope will show you 5-7 thousands deep sky objects, with hundreds of them showing a fair amounts of details (as in previous illustrations).

What is the resolution of a 65 meter diameter radio telescope?

A 65 meter diameter radio telescope observing radio wavelengths of 5 cm would have an angular resolution of 192″. As you can see, the resolution achieved by a typical radio telescope at typical radio wavelengths is not very detailed.

What are the different parameters of a telescope?

A telescope has two important parameters: “Aperture” and “optical quality”. Aperture is the diameter of the objective lens (or a mirror) – it defines how much light the telescope gathers and the maximum resolution (and magnification) it can hope to achieve.

How does the size of a telescope affect the resolution?

The larger the telescope, the more detail can be observed in a given wavelength. Angular resolution (θ) of a telescope can be calculated using the wavelength of light or radio waves (λ) the telescope is being used to observe, and the diameter (D) of the telescope.
