Please note that the Celestron f6.3 Focal Reducer lens is compatible with 5", 6" 8", 9.25", 11" and 14" Schmidt-cassegrains only. For EdgeHD optics, you will need a different focal reducer.
The Celestron f/6.3 Focal Reducer Lens transforms your Schmidt-Cassegrain telescope into a versatile dual-purpose instrument, perfect for both deep-sky imaging and wide-field observations. This lens reduces the telescope's focal ratio from f/10 to f/6.3, improving image quality, widening the field of view, and cutting exposure times for astrophotography. This lens is designed exclusively for Celestron Schmidt-Cassegrain telescopes, including models such as C5, C6, C8, C9.25, C11, and C14. Note that it is not compatible with EdgeHD optics. By reducing the focal ratio by 37%, the lens offers lower magnification for wider views during visual observations and faster exposures for astrophotography.
The focal reducer is simple to attach, threading directly onto the rear cell of your Schmidt-Cassegrain telescope or the reducer plate for larger models like the C11 and C14. Once installed, you can add accessories such as T-Adapters, star diagonals, or off-axis guiders for enhanced functionality.
The lens is housed in durable machined aluminum with a black anodised finish, ensuring long-lasting performance. Internal surfaces are glare-threaded and blackened for maximum contrast, while the fully multi-coated optics provide excellent light transmission and near full-field illumination.
About Celestron
Celestron was founded by Tom Johnson whose first telescope design was a simple 6-inch reflector, built for his young son. He gradually progressed to making larger scopes in more sophisticated designs. Today, the Celestron company is an industry leader in designing and manufacturing optical equipment including telescopes (computerised and non-computerised), binoculars, spotting scopes and its accompanying accessories. Celestron's legacy spans 50 years, and has grown to enjoy recognition from amateurs to serious astronomers globally. The company seeks to remain innovative by growing its product offerings, while supporting science education around the world.
