Telescopes

Posts Tagged ‘star’

In 1609, Galileo Galilei first looked through his telescope, and changed science forever. His discoveries provided solid evidence that disproved the prevailing belief that the Earth was the center of the Universe. Throughout history, scientists such as Johannes Kepler and Sir Isaac Newton further revolutionized the design of the telescope. To celebrate the International Year of Astronomy, Sky-Watcher is proud to present the commemorative edition of Newton’s Telescope – Heritage.

This video is a poorly made and patronising attempt at helping you get the scope onto the tripod correctly and to align it using the 2-star method.

Before you start, you must have entered the date and time into the handset along with your location. Instead of choosing your nearest city, use Google Earth to get your location’s coordinates.

Helpful sites:

Weasner – http://www.weasner.com/etx/menu.html(Everything ETX, fantastic site)

Stellarium http://www.stellarium.org/
(free, stand alone astronomy software. Doesn’t need an internet connection when used, so you can take it with you when using the scope!)
