![]() Or take a look at general space gifts in our Cyber Monday deals live page. Īs well as bagging a Cyber Monday bargain here, we also have deals hubs for Budget telescopes under $500 and our perennial Telescope deals on sale. Entry-level astronomers might be interested in discovering some of the Best telescopes for beginners or for those with smaller hands, the Best telescopes for kids. If none of those take your fancy, why not browse our guides to the Best telescopes, Best telescopes for deep space or Best telescopes for seeing planets. If you're looking for a great holiday gift for someone interested in stargazing, buy them the National Geographic 70 Computerized Refractor Telescope This telescope comes complete with a tripod and two eyepieces to view the heavens in multiple ways. Observe the moon in intricate detail, some of the planets, and even your favorite constellations as the computer hand control guides you across the heavens on a journey of exploration and discovery. This radiation sheds light on the life cycles of stars, the formation of black holes, and the nature of quasars.This computerized telescope will let you explore the night sky like never before. Spitzer scientists often describe their mission as a search for "the old" (the universe's earliest stars and galaxies), "the cold" (brown dwarfs, possibly stars that failed to ignite, and circumstellar discs, broad rings of material orbiting a star) and "the dirty" (dust-obscured processes such as star and planet formation).Ĭhandra captures the rays that emit from the universe's most violent events, such as supernovae. Spitzer is an infrared orbiting telescope that can detect distant or faint sources of radiation that would otherwise be distorted by Earth's atmosphere. The Hubble is just one of NASA's orbiting "great observatories." The group also includes the Spitzer Space Telescope and the Chandra X-ray Observatory. The new instrument will orbit much farther from Earth (940,000 miles/1.5 million kilometers)-the better to peer farther through the dust of space into the earliest formations of stars, solar systems, and galaxies. Its successor, the James Webb Space Telescope, is scheduled for launch in 2013. ![]() The telescope is due for its last periodic servicing in May 2009. Hubble also measures the atmospheres of planets outside our own solar system, exploring their compositions and building data that could someday aid the search for extraterrestrial life.ĭespite its many achievements, Hubble is likely nearing the end of its life. The telescope was also instrumental in the discovery of dark energy, a little-known but ubiquitous force that works against gravity and contributes to the ongoing expansion of the universe. Hubble has also captured images of many ancient galaxies, in all stages of evolution, and so lets scientists see back into the past days of a young and developing universe. Hubble's images have helped to pin down the age of the universe, which the expansion rate of pulsating stars suggests is some 13 billion to 14 billion years. The repair worked, and Hubble began to deliver crystal-clear images. In December 1993 astronauts from the space shuttle Endeavour performed five days of spacewalks to repair the telescope in orbit some 353 miles (569 kilometers) above the Earth. Its images were superior to those of Earth-bound instruments but slightly blurred due to an optical problem. ![]() ![]() When the telescope finally became operational in 1990, it began to return unprecedented but flawed images. The telescope's original October 1986 launch was scrapped after the loss of the space shuttle Challenger. 70 mm reflector telescope w/ panhandlemount (14 pages) Telescope National Geographic NT114CF Instruction Manual. Telescope National Geographic RT70400 Instruction Manual. Scientists began dreaming of such a telescope in the 1940s, but it took more than four decades for those dreams to become reality with the Hubble Space Telescope. Telescope National Geographic 70/350MM GOTO Instruction Manual. Orbital telescopes function as eyes in the sky that allow astronomers to peer farther into the universe and see the cosmos more clearly. Shifting air pockets in the atmosphere block and distort light, limiting the view from even the most powerful Earth-bound instruments. It magnifies 20x to 60x, is exceptionally light, and weighs less than 1000 grams. The telescope also has a 360 degrees rotatable tube that allow you to set a customizable field of view. ![]() It has an objective lens of 60m, a Porro design, and a low-weight. The Hubble Space Telescope was designed to free astronomers of a limitation that has plagued them since the days of Galileo-Earth's atmosphere. The National Geographic Spotting Scope is perfect for mobile use. ![]()
