Though still only in the prototype stage, this flat lens could one day be used on space telescopes, and perhaps even on ...

Other designers proved unable to grind mirrors with a regular curvature, so the reflector remained largely ... however, most optical telescopes in use in the 21st century derive from the two ...

The key to any optical device—and particularly any telescope—is how much light is captured. Here, the Odyssey easily outdoes ...

[Bill Hammack] elaborates on one such piece of engineering: The Alignment Optical Telescope. The telescope was used to find the position of the Lunar Module in space so that its guidance computer ...

New optical technologies have revolutionized astronomy, from the invention of the telescope 400 years ago to more recent developments of adaptive optics and segmented mirrors. The next disruptive ...

Early optical researchers replicated ... most major observatories are Newtonian reflectors. During the nascent years of the telescope, most devices were relatively small, even handheld.

An optical ground station (OGS ... For this reason, the station essentially consists of three components: The most crucial part is the 70cm reflector telescope on a precision mount, that tracks ...

His instrument is a Celestron NexStar, a Schmidt-Cassegrain reflector ... telescope can now be controlled with a Bluetooth gamepad. Astronomy and electronics go hand in hand, whether in the ...

However, its use of Celestron's StarSense smartphone app makes it easy to align and point to celestial targets – and the optical ... telescope like this one. Dobsonians are based on the ...
