Crayford Omegon focuser for Schmidt-Cassegrain telescopes: Surprise with better images In astrophotography, getting the perfect focus is half the job done. But it is not easy to achieve it, especially with a Schmidt-Cassegrain. The reason is that the main mirror of the SC telescope moves during the focusing maneuver. This phenomenon is known asshifting . Avoiding this is as simple as purchasing this Crayford focuser from Omegon that allows precise focusing.
Screw and done! The Omegon Crayford SC focuser is very easy to use. Its thread for connection to a telescope fits perfectly with the standard thread of the SC models. In two minutes everything is attached and ready to go. Overall focus is adjusted via the main mirror while fine focus adjustment is achieved with the new Crayford focuser.
An improved Crayford focuser It is calledBearing Typeto the improved Crayford type design. The standard Crayford focuser already had the advantage of shifting focus, however, the new Omegon focuser has an 8-bearing system that keeps the inner tube always in the correct position. The tube slides smoothly to the desired position. A second toothed bar provides even more stability to the focuser.
High precision: 1:10 reduction The focusing wheels allow you to reach the precise point at all times thanks to their rubber structure. The 1:10 reduction system allows great focusing precision to be achieved even when using large magnification factors, for example when using a laptop.
Load capacity up to 8 kg How are an SLR camera, a large CCD camera, an OAG guidance system and a 2" eyepiece similar? Which are heavy accessories, especially if you use more than one... Luckily this focuser has a large capacity load that allows the use of accessories up to 8 kg. Enjoy observation without worrying about the weight of the equipment...
Astrophotography mode The focus point can be set to make astrophotos possible. The focus mechanism is overridden without altering the settings. In this it also surpasses the traditional Crayford design. The bolt disables the focusing mechanism but does not fix the inner tube, so the eyepiece holder remains centered and the tube is not pressed.
