The Schmidt-Cassegrain optics by Celestron:<\/b><\/p>\n

Despite the\u00a0long focal length<\/b>\u00a0of these telescopes, the OTA itself has a\u00a0very short length<\/b>, making the system a compact telescope which is\u00a0extremely easy to transport<\/b>. Light first hits an aspherically figured Schmidt corrector plate and is then thrown onto a spherical main mirror. This reflects the light back up, throwing it onto a secondary mirror which subsequently throws it back in the direction of main mirror. The light then passes through a central hole in the main mirror and into the focuser at the bottom of the OTA. Thus the\u00a0system is closed<\/b>\u00a0and hence does not suffer from air turbulence which could degrade the image. Of course this also means that the system is optimally protected from dust. The Schmidt plate is multi-coated, ensuring bright images which do not suffer from stray light reflections.<\/p>\n

This telescope provides a\u00a0very good image, boasting high contrast and definition<\/b>\u00a0and provides a lot of pleasure when planetary observing. The Schmidt-Cassegrain design provides a good all-round system suitable for both\u00a0observing and astrophotography<\/b>\u00a0and with an enormous range of optional accessories available. Using the bottom end of the OTA to look through means\u00a0easy orientation<\/b>. The system is also optimal for occasional terrestrial observing, e.g. birdwatching at close range. Celestron SC telescopes have an aperture ratio of around 1:10 which, so astrophotography is also very easily possible.<\/p>\n

Main mirror focusing<\/b>\u00a0means a\u00a0very large range of focus is made available<\/b>, which allows virtually any common accessory to be used. Two pre-loaded ball bearings are used in the main mirror focus positioning mechanism in order to prevent ‘mirror shift’ – a typical problem when using simple bushings. The use of\u00a0high quality materials<\/b>\u00a0such as CNC-milled aluminium components, cast steel and stainless steel guarantees extreme robustness with low weight. This means that a very heavy mount is unnecessary, not always the case for other telescope designs.<\/p>\n
