Two separate 11 m mirrors have the same total area
as a single 15.56 m one.
To find the equivalent single-mirror diameter, you would add the individual mirror diameters and then take the square root. So for two 11m mirrors, the equivalent single-mirror diameter would be √(11m + 11m)^2 = √(242) ≈ 15.56 meters.

Galileo Galilei constructed telescopes to conduct his observations. He also disproved the Ptolemaic model.
The first radio telescope was constructed in 1937 by Grote Reber, an American engineer and radio amateur. He built a single-dish radio telescope in his backyard in Wheaton, Illinois, which he used to map the radio waves coming from the Milky Way.
Telescope eyepieces are important of any visual telescope. It is the main part of the telescope and is what determines how the object will look like through the telescope.
Refracting telescope.
He constructed galileo's telescope, it magnified ten times than a regular telescope.
A telescope he constructed himself from an earlier Dutch model.
-- A refracting telescope must have a lens, otherwise it's not a refracting telescope. -- A reflecting telescope can be constructed without any lens, but if you intend to look through it, then you'll use a little lens for the eyepiece.

He invented (or at least constructed the first known working version of) the telescope.
Edwin Hubble did not build the Hubble Space Telescope. The Hubble Space Telescope was constructed by NASA and was launched into space in 1990. It was named after Edwin Hubble, who was a prominent astronomer known for his contributions to the field of cosmology.
The first binocular telescope, consisting of two telescopes placed side by side, was. constructed in 1608 by Johann Lipperhey, the inventor of the ordinary Dutch telescope. hope this helps i saw it on another question quiet similar 2 this one .
The Hubble Space Telescope weighs about 24,500 pounds (11,110 kilograms), which is roughly the equivalent of two full-grown elephants.

He constructed the 13 inch reflecting telescope mounted at Canonbury. He invented the Photoheliograph for the representation of the state of lunar surface. His main inventions were in Solar Physics.
