The Celestron C5 Spotting Scope is a 5" (127mm ) diameter Schmidt-Cassegrain telescope with a focal length of 1250mm and a focal ratio of f/10. Its excellent optics is the reason it was selected by NASA for several space missions.
This telescope Celestron is an ideal choice for ornithology enthusiasts, nature lovers or for anyone who enjoys the wonderful views that can be seen from the top of a mountain. Weighing only 3Kg and 28cm in length, it is a fully portable telescope for visual and photographic observation.
On the other hand, CELESTRON offers a wide variety of accessories to get the most out of this special instrument. The diameter of the C5 allows it to easily surpass the performance of any of the smaller aperture spotting scopes. With 4.5 times the light gathering power of a 60mm telescope, and 2.5 times that of an 80mm telescope, the CELESTRON C5 is the brightest and the instrument you need when you want bright, contrasty images.
The C5 Spotting Scope is an extraordinarily versatile telescope, and its close minimum focusing distance of approximately 6m makes it easy to observe all types of flora, fauna, birds or insects. At the same time, the C5 can also be used as an astronomical telescope.
In addition, the C5 can easily be converted from a telescope to a long-range telephoto photographic lens with a focal length of 1250mm and a brightness of f/10. Photography could never be easier, as the C5 is designed to be fully adaptable to today's cameras.
In order to take professional quality photographs, simply purchase the optional T-adapter and T-ring that matches your camera model and attach them to the back of the C5 tube along with the camera body and start shooting.
At the bottom of the tube is an adapter block for easy attachment to a tripod. The C5 comes complete with its own (soft) carrying case.
