Edmund Scientific Corporation, based in Barrington, New Jersey, was founded in 1942 as a retailer of surplus optical parts like lenses.It later branched out into complete systems like telescopes and microscopes, and in the 1960s, a wide variety of science toys and kits.
When Edmund Scientific introduced the telescope in 1976 they called it "The Edmund Wide-Field Telescope" with a Part Number "2001" [5] Edmund had a public contest which ran until November 15, 1976, to come up with a name. [6] The winning name was "Astroscan 2001". The "2001" part of the name was dropped over time.
The telescope of the historic "Y" level is held in two brass arms, which are part of the mount and the telescope could be easily removed to allow sighting reversal though 180 degrees or an axial rotation of the telescope; both to compensate for optical collimation errors. Because the telescope is not fixed to the level adjusting mechanism, the ...
The Cosmic Origins Spectrograph (COS) is a science instrument that was installed on the Hubble Space Telescope during Servicing Mission 4 in May 2009. It is designed for ultraviolet (90–320 nm) spectroscopy of faint point sources with a resolving power of ≈1,550–24,000. Science goals include the study of the origins of large scale ...
There are many applications for ULE, but by far the most common is for mirrors and lenses for telescopes in both space and terrestrial settings. One of the most well known examples of the use of ULE is in the Hubble Space Telescope's mirror. Another good example of its application is in the Gemini telescope's mirror bank. This type of material ...
An airborne observatory is an airplane or airship with an astronomical telescope. By carrying the telescope to a sufficiently high altitude, the telescope can avoid cloud cover, pollution, and carry out observations in the infrared spectrum, above water vapor in the atmosphere which absorbs infrared radiation. Some drawbacks to this approach ...

Since it was too difficult to bring the HST back to earth for repairs the engineers considered everything from replacing the telescope's secondary mirror by sending a spacewalking astronaut into the telescope's optical tube, to installing a circular shade around the opening of the tube, which would reduce the aperture and improving the focus by ...
