If you don’t want an electronic GPS function, the Astronomers Without Borders OneSky Reflector Telescope offers the most scope for the money. So you should have no problem packing it into a trunk and setting it up on location.
#Most expensive telescope for sale portable
This scope weighs 15 pounds, making it very portable relative to other options out there. Unlike with some of the NexStar 5SE’s competitors, this controller worked flawlessly in our tests, offering micro adjustments and responsive tracking with the attached controller system. Instead of fumbling to read star charts and align the telescope manually, with the press of a button you can align and focus your telescope on a myriad of celestial objects. The NexStar 5SE operates on a fully computerized system and gives you a handheld controller to guide it.
And it provides sufficient power to introduce you to objects in the deep sky. This telescope has a primary 5-inch mirror-big enough for a light-gathering capacity that yields crisp images of some of the best objects in our solar system, from Saturn’s rings to Jupiter’s cloud bands.

Many of the problems the team had to overcome required wholly new technological solutions that used techniques and designs that had never been tried before – these technologies also had to be manufactured to impossibly high standards as they would have to work flawlessly first time. The design and construction of such an ambitious project proved to be vastly more challenging than anyone had anticipated, however. NASA awarded the first construction contracts in 2003, with an expected budget of $825 million and a planned launch date of 2010. This is a location where the gravitational forces of the Sun and Earth are perfectly balanced, allowing the JWST to orbit the Sun in unison with Earth, but far enough away for its sunshield to be able to block out our planet.ĭevelopment of the JWST started in the early 1990s, around the time that the Hubble Space Telescope launched. To prevent the faint signals it is being designed to detect being drowned out by relefected light from Earth, JWST is located some 1.6 million km (1 million mi) away in an orbit around a position called the Earth-Sun Langrange Point 2.

The mirror is designed for optimal reflectivity in the infra-red wavelength, and channels light to a series of instruments optimized for particular aspects of its science mission. Every 1.32-m (4-ft 3-in) segment is adjusted using motors capable of nanometre-level precision, allowing them – once calibrated – to function as a single 6.5-m diameter mirror.
The primary mirror, which also had to be unfolded in space, is made from 18 hexagonal segments, each made from berylium coated with a microscopic layer of gold. This is a 21.19 m (69 ft 6 in) long and 14.16 m (46 ft 5 in) wide expanse of lightweight kapton which was unfolded and tensioned as the spacecraft travelled away from Earth. The most important, and technically challenging, of these os the telescope's multi-layer fabric sunshield. The James Webb Space Telescope is a novel design that incorporates many design elements that had never been flown on a spacecraft before. The European Space Agency's costs were estimated at €700 million ($792 million), but this also includes the roughly $175 million cost of the Ariane 5 launch rocket. In addition, the Canadian Space Agency contributed the FGS/NIRISS (Fine Guidance Sensor and Near Infrared Imager and Slitless Spectrograph) instrument at a reported cost of CAN$200 million ($156 million) and the European Space Agency provided the NIRSpec (Near InfraRed Spectrograph) instrument and elements of the MIRI (Mid-Infrared Instrument). The bulk of the costs were borne by NASA, whose contribution to the telescope's development was estimated in 2021 to have come to $8.8 billion. At the time of the JWST's launch on 25 December 2021, an additional $861 million had been allocated to support the first five years of the telescope's operation. The most expensive single spacecraft is the James Webb Space Telescope (JWST), which is estimated to have cost $9.5 billion (£7 billion) to design and build between 20.
