Two separate 11 m mirrors have the same total area
as a single 15.56 m one.

Galileo Galilei constructed telescopes to conduct his observations. He also disproved the Ptolemaic model.
The first radio antenna used to identify an astronomical radio source was one built by Karl Jansky, an engineer with Bell Telephone Laboratories, in 1931. Jansky was assigned the job of identifying sources of static that might interfere with radio telephone service.
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.
simplest possible 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 .
On Earth, the Hubble Space telescope weighs 11,110 kg (24,500 lb)
Galileo Galilei constructed telescopes to conduct his observations. He also disproved the Ptolemaic model.
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.
