What kind of telescope did newton invent

Although the INT itself was acquitting itself at Herstmonceux, the weather at the site was not ideal. With the advent of mass air travel it was plausible for UK astronomers to run an overseas observatory.

In , the INT was shipped to the top of the mountain at Roque de los Muchachos Observatory on the island of La Palma where it continues working to this day. It saw its second first light in , with a video camera. A major change was the mirror. The original Pyrex mirror was replaced by a larger inch 2.

The other main instrument available at the INT is the Intermediate Dispersion Spectrograph IDS , recently re-introduced having been unavailable for a period of several years. Dismantling the INT in the late s was the beginning of the end for Herstmonceux. With the telescope transferred to La Palma there was little cause for keeping the estate on.

Astronomy was changing. With cheap air travel astronomers could work in little offices anywhere and jet off to the big mountaintop observatories around the world for their observing sessions. So with much heartache and recrimination Herstmonceux closed in , a sad end to the all-too-brief Golden Age of Astronomy at Herstmonceux.

The remnants of the observatory moved to an office block in Cambridge, and finally, in it closed altogether as an observing establishment, after years.

Newton thought that it would be impossible to get rid of chromatic aberration as long as lenses were used in telescopes.

Newton started working on another type of telescope that he thought should get rid of chromatic aberration.

Instead of using a lens to focus the light from a star, Newton used a mirror. He experimented with different metals and polishing methods and made his first reflecting telescope in Newton was not the only astronomer to think of building a telescope with a mirror, but he was the first to produce a working reflecting telescope.

His telescope was shown to the Royal Society of London , one of the most distinguished organizations promoting science. The demonstration was so successful that Newton was elected to membership to the Royal Society immediately. He proved via mathematics that while the earth pulled on a falling apple, the apple too pulled on the earth. Skip navigation Accessibility information.
