Huygens and the biggest telescopes of the 17th Century

Christiaan Huygens was born in Holland in 1629 and he was a mathematical genius who  invented several important mechanical devices including the pendulum clock.  He had a deep understanding of astronomy, optics, mathematics, and mechanical devices.  And he built some of the largest telescopes of the 17th century.

Christiaan Huygens was born in Holland in 1629 and he was a mathematical genius who  invented several important mechanical devices including the pendulum clock.  He had a deep understanding of astronomy, optics, mathematics, and mechanical devices.  And he built some of the largest telescopes of the 17th century.

Being a contemporary of Galileo he heard about Galileo’s telescope and he set out to improve on the design. One of the liabilities of refracting telescopes like the one that Galileo built was that because of optical problems they caused distortion in how things looked. The colors of objects were separated and things were not sharp. This was a phenomenon called chromatic aberration. Huygens discovered, after much experimentation, that this problem could be lessened by building lenses with much longer focal lengths. This type of lens with a longer focal length was easier to make accurately. And using this discovery he built telescopes that were as long as 120 feet.

He called his style of telescope “tubeless” because it was an open air frame without a tube; and while he did build a monster that was 120 feet long it was cumbersome and difficult to use. Most of his observations and discoveries were made with smaller telescopes around forty feet in length.

He wasn’t just a lens and telescope maker though. He was also an avid astronomer and he used his telescopes to make some discoveries under the night sky. One of his most important discoveries was of the rings of Saturn. He wasn’t the first one to actually see them. Galileo did that. But because of chromatic aberration Galileo’s telescope wasn’t good enough to resolve the rings into what they truly were. All Galileo saw was what he described as a tri-form planet which was composed of a large center section that had a section attached to each side.  He described these side sections as being much like the handles of a vase.  Huygens, with his better telescopesArticle Search, could resolve the image of Saturn better and see what was really there and in 1656 he published his findings. He described Saturn as being composed of a central globe much like Jupiter but girdled by a thin flat ring that did not touch it.

 Other discoveries by Huygens

 He also discovered Titan which is the first of Saturn’s moons.  And his sketches of the Orion nebula are the first known sketches of it and today the center of this nebula is named after him as the Huygens region.  He also discovered several interstellar nebulae and some previously undiscovered double stars.

Huygens isn't very well known in modern times but he made some important contributions to the science of astronomy with his discoveries and to the art of telescope making with his work in optics and chromatic aberration.  He also built the largest telescopes of the seventeenth century.
