Orion SpaceProbe 130 EQ Reflector
List Price:  |
DescriptionThe Orion SpaceProbe 130 EQ Reflector is a Newtonian reflector telescope packaged with a sturdy equatorial mount, two Explorer II eyepieces, a 6x30 finder scope, and Orionâs Starry Night Special Edition software. Invented by Sir Isaac Newton, reflector telescopes provide more light gathering power per dollar than any other telescope design. With 130mm (5.1 inches) of aperture, the SpaceProbe 130 produces images that are twice as bright as 90mm telescopes and more than four times brighter than 60mm beginner scopes. The Orion SpaceProbe 130 EQ Reflector with its Explorer II eyepieces serves up bright, clear images of the Moon, the planets, and even deep space objects like star clusters and galaxies. The 25mm eyepiece magnifies the image by 36 times; when I look at the Pleiades or Seven Sisters cluster at 36X the SpaceProbe 130 shows me a bright open cluster with dozens of point-like stars filling the field of view. When I use the 10mm eyepiece (90X magnification) the lunar disk fills the field of view and the rings of Saturn are plainly resolved. And when I use an optional Ultima 2X Barlow with the 10mm eyepiece for 180X magnification I can see the cloud bands of Jupiter and pick out individual stars in bright globular clusters like M13. The EQ2 equatorial mount included with the Orion SpaceProbe 130 EQ Reflector comes partially assembled, but it shouldn’t take long to set up. The trick to using an equatorial mount is to point the polar axis at Polaris, the North Star. Once the mount is aligned and balanced, the telescope tracks stars and planets at high power with just a turn of one slow motion knob. You can even add an optional motor drive for hands free tracking. The Orion SpaceProbe 130 EQ Newtonian Reflector Telescope is a simply a great value. The Explorer II eyepieces deliver bright sharp images of the Moon, the planets and the stars, and the EQ2 mount can be motorized for hands free tracking. --Jeff Phillips Pros: More than 4 times brighter than 60mm scopes Includes two eyepieces and a 6x30 finder Solid equatorial mount and aluminum tripod Starry Night software and SkyTheatre DVD included Ships to the U.S. including Alaska, Hawaii, and Puerto Rico.

All served in crisp detail by way of the SpaceProbe's light-gathering 130mm (5.1") primary mirror of 900mm focal length (f/6.9). The mirror lies at the base of the rolled-steel optical tube, which is outfitted with a smooth rack-and-pinion focuser. It accepts 1.25" telescope eyepieces, including the two fully coated Explorer II telescope eyepieces that come standard with the Orion SpaceProbe 130mm: a 25mm for low-power viewing at 36x and a 10mm for higher-power looks at 90x. Also standard is a 6x30 achromatic finder scope to help home in on celestial targets. The mount is our sturdy EQ-2 equatorial model, with adjustable aluminum legs and accessory tray.

Sights of interest from a replica of the Great Telescope
A telescope is an instrument designed to look in distant places. The first were created and in the 11th century by Arab scientists. This era was known as the Golden Age of Islam and the invention of the optical lens that would later lead the development of the first telescope was one of the many inventions of many other 'firsts' for Arab and Muslim scientists.
Large mirrors telescope only came much later. These reflectors were designed to reflect light in such a way as to reveal or highlight the shaded areas. Glass mirrors the large telescopes (which was coated silver) were replaced by metal mirrors in reflector telescopes only mid-nineteenth century. At the time it was considered a great improvement in the quality of the telescope.
Modern Telescopes
Large telescopes have been developed and have improved greatly over the decades. The latest telescopes are only as good as the performance of their reflectors. A reflector is designed to redirect light. Sunlight or Starlight is absorbed and redirected by the reflector. The main objective of this redirection is to allow the viewer to observe in situ or areas that are shadowed or hidden. This makes it ideal for deep space probe.
The more the object, the larger the reflector. Huge floodlights are now in the observatories worldwide. To be able to see what is happening in areas of deep space, large telescope mirrors have been designed and built in these reflectors. These mirrors of large telescopes are specially designed and technically designed to reveal more details about everything.
Observed from Images large telescope mirrors are often impressive. Due to the finer details are revealed reflector telescopes on the moon and distant planets. The huge number of nebulae stars, as well as groups may find it easier to identify. For the amateur astronomer is relatively easy to build a reflecting telescope with a large telescope mirror from the beginning. After a tour in space tourism will have a majority of the fans to go bigger and better.
Where are you?
The telescope bigger and more colorful that was put into space was of course "The Hubble telescope." After a initial failure in one of its scientific mirror occasionally go into space to service Hubble. Due to the ability of the Hubble images to reflect more deep-space clear and precise which has allowed astrophysicists to unravel many advances.

The Perfect Machine: Building the Palomar Telescope
List Price: |
DescriptionAlmost a half-century after is completion, the 200-inch Palomar telescope remains an unparalleled combination of vast scale and microscope detail. As huge as the Pantheon of Rome and as heavy as the Statue of Liberty, this magnificent instrument is so precisely built that its seventeen-foot mirror was hand-polished to a tolerance of 2/1,000,000 of an inch. The telescope's construction drove some to the brink of madness, made others fearful that mortals might glimpse heaven, and transfixed an entire nation. Ronald Florence weaves into his account of the creation of "the perfect machine" a stirring chronicle of the birth of Big Science and a poignant rendering of an America mired in the depression yet reaching for the stars.
