A 10 inch reflecting telescope provides common optics for infrared and electro-optical sensors. |

Snap would orbit a three-mirror, 2-meter reflecting telescope in a high orbit over Earth's poles, circling the globe every week or 14 days. |
|
The Newtonian telescope is a type of reflecting telescope still in popular use. |
|
In 1973 she built a reflecting telescope with a nine-inch mirror that she ground and polished herself. |
|
The school's Newtonian reflecting telescope gave hundreds of the pupils the chance to watch the transit live on a projected screen. |
|
He made his reflecting telescope entirely on his own, some parts of it with tools that he made specifically for the purpose. |
|
He developed a general rule for the focal length of lenses and described a reflecting telescope. |
|
He built a reflecting telescope, polishing the mirror himself, and began observing the stars. |
|
During my junior year in high school I built a reflecting telescope with mount and drive made of parts salvaged from a junkyard. |
|
He has a 10in reflecting telescope that stands more than 9ft tall and dominates his back garden in Worcester. |
|
Indeed, it may go back as far as Sir Isaac Newton, the inventor of the reflecting telescope. |
|
At some point, you will want to add a refracting or reflecting telescope to push your observations to the next level. |
|
Sometime between 1540 and 1553, the English mathematician Leonard Digges constructed the first reflecting telescope using a mirror and a lens. |
|
Today, the reflecting telescope is considered as one of the most powerful scientific instruments ever invented. |
|
He therefore proposed and constructed a reflecting telescope. |
|
The mammoth 19-inch reflecting telescope, one of the largest public telescopes in northern England, is housed in its own dome at the forest visitor centre. |
|
The huge framework of the reflecting telescope loomed before me, the two-ton Pyrex glass mirror at the bottom, the tube pointing up and out through the aperture in the dome. |
|
In 1671, the Royal Society asked for a demonstration of his reflecting telescope. |
|
The reflecting telescope predominated in the 20th century. |
|
Before we get to this week's subject, it is worth noting that among many other things, Newton invented the reflecting telescope, which uses a mirror to collect the light and form the image. |
|
|
In order for light rays to be concentrated at the focal point of a reflecting telescope, the size of the irregularities in the curve of the parabolic collector must be smaller than the wavelength of the light being collected. |
|
For the infrared domain, the parabolic mirror of a reflecting telescope remains the ideal means by which to collect and concentrate the light rays. |
|
In 1663, the Scottish mathematician and astronomer James Gregory published his book Optima Promota in which he included the design for a new type of compact reflecting telescope. |
|
The focal ratio of the telescope was ideal for the stellar spectroscopy at the Observatory, and its asymmetrical mount gave it access to most of the sky, the first of this type for a reflecting telescope. |
|
However, he was able to demonstrate that the angle of reflection remained the same for all colors, so he decided to build a reflecting telescope. |
|
It was completed in 1668 and is the earliest known functional reflecting telescope. |
|
In late 1668 he was able to produce this first reflecting telescope. |
