description

Please note: this is a bulky item and therefore cannot be shipped internationally.

The Celestron CPC GPS 1100 telescope has a computerised mount and features a database of over 40,000 celestial objects, user-defined objects and includes expanded information on over 200 objects. The Celestron telescope is perfect for viewing deep space objects and astrophotography, with the duel fork arm making it more stable for attaching cameras. 

What will I be able to see with the Celestron CPC GPS 1100?

  • Lunar features under 2km across
  • Internal detail in nebulae including star birth regions, and visible structures in many galaxies from a dark sky site
  • Large clouds and dust storms on Mars
  • The Cassini Division and Encke Gap in Saturn's rings often visible
  • Advanced detail of weather systems of Jupiter and small features of Jupiter's four Galilean moons
  • Thousands of globular clusters with detail, resolved almost to the core
  • Double stars separated by less than 1 arcsecond
  • Faint stars down to magnitude 14
  • Increased aperture from the CPC 925 will mean that faint fuzzies will be able to be seen in greater detail

Some objects may require additional eyepieces to see clearly, sold separately. Visibility subject to local conditions and positions of objects.

GLOSSARY OF TERMS

  • Schmidt Cassegrain: a type of telescope that uses a thin Schmidt correcting lens, a spherical primary mirror and a small secondary mirror to focus light through the eyepiece at the rear
  • Aperture: the size of the main mirror that collects light.
  • Focal length: the distance between the centre of the mirror and the point of it being focused by the eyepiece – the higher the focal length, the greater the magnification.
  • Focal ratio: focal length divided by aperture.
  • Magnification: a calculation of the focal length of the telescope over the focal length of the eyepiece.
  • Alt-azimuth mount: a mount that allows movement in altitude (up and down) and azimuth (side to side).
  • Optical coating: a thin layer of material on an optical component such as a lens or mirror which alters the way in which light is reflected or transmitted. StarBright XLT improves light transmission for both visual and photographic purposes.
  • Finderscope: a low power scope attached parallel to the main telescope, which provides easy telescope aiming.
  • Star Diagonal: an angled mirror or prism that allows viewing from a direction that is perpendicular to the usual eyepiece axis. The resulting image is right side up, but is reversed from left to right.
  • Highest useful magnification: the highest visual power a telescope can achieve before the image becomes too dim for useful observing.
  • Lowest useful magnification: the lowest power usable from a dark sky observing site. An eyepiece with still lower power has an exit pupil (the beam of light coming out of the eyepiece) larger than the pupil of your eye.
  • Limiting stellar magnitude: the faintest star you can see with a telescope (under excellent seeing conditions). The limiting magnitude is directly related to aperture, where larger apertures allow you to see fainter stars.
  • Angular field of view: the extent of the observable world that is seen at any given moment. The angular field of view is that viewed by the instrument in square degrees.
  • Linear field of view: a ratio of lengths and refers to the area that can be observed at 1,000 yards.
  • Photographic resolution: how close dark and light lines can be to each other and still be visibly differentiated.
  • Light Gathering Power: a telescope's theoretical ability to collect light compared to your dilated eye.
  • Secondary mirror obstruction: a secondary mirror is required to send the light from the main mirror to the correct position for viewing. This mirror and its holder obstructs some of the light entering the telescope.
  • Slew speeds: the speed that the controller moves the telescope. Speeds are calculated to accomplish specific functions.
  • Tracking rates: in addition to the Earth’s rotation, the computed tracking rates take many additional factors into account such as the Earth’s orbit around the Sun, the Moon’s orbit around the Earth, and an object’s position relative to the horizon.
  • Periodic Error Correction: trains out periodic errors in the worm gears. This should be done with autoglider software such as Meta Guide, which then applies the tracking corrections to normal mount use.
