There is an optical companion to Iota Librae; 25 Librae is a star of magnitude 6.1‚ 219 light-years from Earth and visible in binoculars. Mu Librae is a binary star divisible in medium-aperture amateur telescopes‚ 235 light-years from Earth. The primary is of magnitude 5.7 and the secondary is of magnitude 6

Another flaw was that he believed that the Earth was the centre of the universe and the Sun‚ Moon and all other planets revolved around it.

of Saturn’s moon Titan. Huygens would grind his own lenses for his telescope and invented what is now known as the Huygenian eyepiece. He was also known for his work as a physicist‚ probabilist‚ and horologist. Placing two plano lenses in a telescope‚ separated by an air gap‚ creates the Huygenian eyepiece. The lenses should have the plane sides facing the eye. These eyepieces are best used in long focal length telescopes. These lenses are no longer used today but during Huygens’ time‚ they

Telescope... A telescope is an instrument that aids in the observation of remote objects by collecting electromagnetic radiation (such as visible light). The first known practical telescopes were invented in the Netherlands at the beginning of the 17th century‚ using glass lenses. They found use in terrestrial applications and astronomy.Within a few decades‚ the reflecting telescope was invented‚ which used mirrors. In the 20th century many new types of telescopes were invented
