Collins Night Sky & Starfinder Book - £9.00 off SRP
The ideal introductory guide for novice stargazers, Collins Night Sky & Starfinder is a comprehensive look at the stars, planets and astronomical events – complete with loads of useful photos and illustrations. With sections on how to observe and understand the different components that make up the night sky, this informative book includes a circular starfinder tool that will help you identify the arrangement of stars above on any given date.
Computer controlled telescopes
Computer controlled astronomical telescopes have digital databases that guide telescopes and telescope mounts to your target. They were originally developed in the 1960's, when electronic circuits were incorporated into telescopes. Today they possess high speed 'slewing' motors, which cause the telescope to rotate quickly upon the axis, precisely centring on the object in the sky.
Telescope eyepieces come with variable sizes, and can be interchanged for increased and decreased magnification. Popular features are colour correction, adjustable eye points and lanthanum glass for high contrast viewing. They vary in size and measurement according to the specific objects that you wish to observe.
Telescope mounts provide an axis upon which the telescope can change direction and manoeuvre for precise tracking. Al-azimuth mounts have a basic design, rotating at variable rates about a pair of axis.
Equatorial mounts are more advanced and have one rotational axis, which is parallel to the rotation of the earth's axis. The axis is driven at a constant speed allowing the telescope to stay fixed on the object in the sky.
Celestron and Goto telescopes
Goto telescopes are computer controlled telescopes built for the observation of astronomical objects. The user can set the programme by inputting the relevant data, whereby the axis of the telescope will meet the correct ascension and declination for your object.
Celestron telescopes have led the way for computer controlled telescopes. At Sherwoods we have a comprehensive range of Celestron products for both the seasoned astronomer and those just starting out.
Our Celestron telescopes come with a range of features and software that make them simple, accurate and easy to assemble.
