We decided to drop all other plans for that evening, and went for a spectral observation with SALT, since you need a large telescope for such observations breaking up the light into all its colours.

(c) Many amateur astronomers today use catadioptric telescopes.

SALT and other SAAO telescopes have provided some of the very first data in what is turning out to be one of the most-studied astrophysical events ever. Several pipes—so-called casings—are installed in this well in a telescope-like arrangement and bonded with cement to the surrounding rock to make the casings gas tight. SALT is funded by a consortium of international partners from South Africa, the United States, Germany, Poland, India, the United Kingdom and New Zealand. And what he saw would forever revolutionize the field of … Some of us have looked at getting a telescope, gone down to the store, and seen telescopes going for prices between $200 all the way up to the fancy $8,000 mark. Several men laid claim to inventing the telescope, but the credit usually goes to Hans Lippershey, a Dutch lensmaker, in 1608. Southern African Large Telescope (SALT) Overview. Salt, of course, has many uses; some techniques using salt such as production of "salt prints" in 19 th Century photography have been superseded by new technologies, but others have not. Construction involves drilling a well deep into the rock salt with a diameter of d < 1 m (Fig. In the Starry Messenger, Galileo had used the term perspicillum. I … The word telescope (from the Ancient Greek τῆλε, tele "far" and σκοπεῖν, skopein "to look or see"; τηλεσκόπος, teleskopos "far-seeing") was coined in 1611 by the Greek mathematician Giovanni Demisiani for one of Galileo Galilei's instruments presented at a banquet at the Accademia dei Lincei. Several men laid claim to inventing the telescope, but the credit usually goes to Hans Lippershey, a Dutch lensmaker, in 1608. It's also affordable, easy to use, and harmless when used appropriately. Asked in . In 1610, Italian astronomer Galileo Galilei looked up at the heavens using a telescope of his making. What are the advantages of the SALT telescope? 1995 - The Hubble telescope takes the deep field image which is arguable the most profound astronomical image ever taken, along with the Hubble Ultra deep field (2003-2004) and Hubble Deep Field Sount (1998) 2005 - The Large Binocular Telescope (LBT) achieves first light. carnun writes "On the 1st of September, 5 years after ground breaking, the SALT Telescope released their first light images to the public. 19.6). Since its launch in 1990, the Hubble Space Telescope (HST) has provided a dazzling array of images that have awed and inspired the public. This new telescope also possessed a thicker, clearer, 2 in diameter spectrum, which improved viewing image quality. I used Autostakkert, Registax and Photoshop for post processing. Telescopes. South Africa's Salt telescope (pictured) has once again surprised astronomers by helping to detect the first white dwarf pulsar. It was not the first space telescope but it is one of the largest and most versatile, well known both as a vital research tool and as a public relations boon for astronomy. Salt is even associated with the struggle for women's rights in the U.S. The Hubble Space Telescope (often referred to as HST or Hubble) is a space telescope that was launched into low Earth orbit in 1990 and remains in operation. SALT’s primary mirror consists of 91 smaller hexagonal mirrors, each with sides 1 m long. Well SALT is much bigger, it has a 10m mirror compared to HST’s 2 meters. However, not all American "salt history" is so old. Radio telescopes have also been put into space and a virtual telescope even larger than the size of the Earth can be created by using orbiting radio telescopes.
