Astromania Telescope Focal Reducer Corrector f/6.3 for Schmidt-Cassegrain

Astromania Telescope Focal Reducer Corrector f/6.3 for Schmidt-Cassegrain

• 37% Focal Length Reduction means F/6.3 focal reducer shortens the effective focal length of a Schmidt-Cassegrain telescope optical system by 37 percent — transforming your f/10 system into a faster f/6.3 configuration for significantly wider field of view
• The focal ratio changes by the same amount from 1:10 to 1:6.3 that effectively shortens the required exposure time by a factor of 3 while widening the true field through eyepiece; Remains one of the most versatile focal reducer accessories for SCT owners
• F/6.3 focal reducer is designed with an SCT thread for all Celestron Schmidt-Cassegrain telescopes (5", 6", 8", 9.25", 11" & 14") including NexStar SE, Evolution, and EdgeHD series; Universal SCT compatibility for making it the ultimate sct focal reducer
• This F/6.3 focal reducer fits the standard SCT rear-cell thread directly with no adapter needed; Whether you call it a sct telescope adapter or a f6.3 focal reducer this unit provides the same reliable twist-on installation for a secure image train
• Features 4-element fully multi-coated optics with 41mm clear aperture to ensure maximum transmission and minimized chromatic aberration for crisp celestial views; This f6.3 focal reducer delivers clean contrast-rich images on planets Moon and deep-sky
• Designed to work as a reducer corrector lens and telescope reducer corrector it maintains sharp stars across the field; Add a F6.3 reducer to your visual or imaging setup and you get the benefits of f6.3 reducer corrector without sacrificing image quality
• The essential f/6.3 reducer-corrector for deep-sky imaging is a clever telescope accessory that makes it possible to have a dual focal ratio instrument without sacrificing image quality during astronomical observation
• Telescope reducer adopts CNC-machined aluminum alloy with a shock-absorbing rubber housing that complete with dust caps and storage case — protecting the focal reducer from impacts and moisture during transport and storage
