C5 Schmidt-Cassegrain - 125 mm Aperture, 1250 mm Focal Length
The C5 is one of the classics in Celestron´s product range. It is equally suited for astronomical applications as well as for photography and for nature observations. C5 optics have even been used by NASA for some Space Shuttle missions!
This instrument is excellent in image quality and is particularly versatile, making it ideal for a broad variety of users.
ApplicationsThe Celestron C5 combines a large light gathering power, a long focal length and very compact dimensions. It is ideal under awkward light conditions or during the night-time. For photography the C5 resembles a very powerful telephoto lens with 1250 mm focal length and a focal ratio of f/10.
Compact and Ultra-portableWith a length of only 33 cm and a weight of 2.7 kg the C5 is extremely compact and portable for an instrument with this light-gathering power and resolution. It can even be mounted on a sturdy camera tripod. We consider the C5 to be suitable even for airline travelling.
Spotting scopeThe C5 is a powerful spotting scope for nature observing and birdwatching. Under good conditions you can use magnifications up to approx. 200x! A large number of eyepieces is available - you can choose between hundreds of eyepieces from dozens of brands. One particular application of the C5 is target shooting. Under good conditions you can even see where you hit a target at 300 m shooting distance!
Extremely versatile - a large number of accessories can be usedThe internal focusing mechanism provides a major advantage: Almost any accessory can be used on the C5 that cannot be used on many other telescopes. This includes, among many others:
1.25" visual back for attachment of standard accessories adaptations for various cameras (optional) adaptation of binocular viewers for observing with both eyesXLT coating for a brighter imageThe C5 comes with Celestron´s most powerful coating: the XLT coating. As a result, over 10% more light reaches your eyes than with other comparable telescopes. The result: a brighter image and more contrast.
