View Images Library Photos and Pictures. Richest Field Telescopes 8" f/6 classic tube Dobsonian Telescope by Pinbout, Stellafane 2012. Do you like all the outstanding features of the AstroSystems TeleKit but don't have the time, space or inclination to build one? Not a problem! THE MOST ADVANCED TRUSS TELESCOPE ON THE MARKET. The green beam of light and red lunar disk are real enough, captured in the early morning hours of April 15. Of course, the reddened lunar disk is easy to explain as the image was taken during this week'stotal lunar eclipse. Immersed in shadow, the eclipsed Moon reflects the dimmed reddened light of all the sunsets and sunrises filtering around the edges of planet Earth, seen in silhouette from a lunar perspective. But the green beam of light really is a laser. Shot from the 3.5-meter telescope at Apache Point Observatory in southern New Mexico, the beam's path is revealed as Earth's atmosphere scatters some of the intense laser light. The laser's target is the Apollo 15 retroreflector, left on the Moon by the astronauts in 1971. By determining the light travel time delay of the returning laser pulse, the experimental team from UC San Diego is able to measure the Earth-Moon distance to millimeter precision and provide a test of General Relativity, Einstein's theory of gravity. Conducting the lunar laser ranging experiment during a total eclipse uses the Earth like a cosmic light switch. With direct sunlight blocked, the reflector's performance is improved over performance when illuminated by sunlight during a normal Full Moon, an effect known as the real Full Moon Curse.

Collimation with a Laser - Orion Telescopes and Binoculars

Wednesday, Sept. 3, 2014: A yellow laser beam appears to fan out across the sky over the Allg�u Public Observatory in Ottobeuren, Germany. A long exposure time makes the thin beam spread out in the image, on a night when the observatory was examining the Northern Celestial Pole. The instrument seen here is the facility's 0.6-meter Cassegrain reflector telescope, dating back to 1996. The laser provides a guide star, which can serve as an artificial reference star to help calibrate the ...
