  • The Celestron 6" SCT Optical Tube Assembly has a stunning 459x more light gathering power than the human eye!
  • Celestron's state of the art StarBright XLT coatings improve light transmission significantly for a better visual and or imaging experience.
  • The correcting plate and mirror design avoid many of the aberration issues found in refractors, therefore creating less optical disturbance.
  • The f/10 focal ratio of the Celestron 6" SCT makes it a decent optical instrument to have for longer exposure, but adding the optional (sold separately) focal reducer will create an f/6.3 application; making it more suitable for shorter exposure and larger sensors.

Celestron - C6-A-XLT - 6" SCT Optical Tube Assembly for (CG-5) - 91010-XLT

The Celestron C6-A XLT is a 6” Schmidt-Cassegrain optical tube(only) has a light gathering power of 459x compared to the human eye. This is outstanding even when you factor in Celestron adding in its own StarBright XLT coatings for improvements to light transmissions. With a focal length of f/10, it is a mid-range for Schmidt-Cassegrain designs. Since it is a “hybrid” between both reflectors and refractors, using a correcting plate as well as mirrors, it is devoid of many of the chromatic aberration found in normal refractors using primary lenses. While the focal ratio is quite slow for deeps sky observing, using the optional focal reducer (sold separately) will transform this telescope into a f/6.3, making it a much faster instrument and more suitable for larger sensors or astrophotography with larger pixels. However, even without this add on, planetary and terrestrial objects will look outstanding. Visual observers will have a few accessories already included to enjoy using. This will include a 25mm eyepiece that will result in a 60x magnification, star diagonal, visual back for 1.25” accessories, and a 6x30 finderscope. For the C6-A XLT optical tube, there is a dovetail rail that is designed to be compatible to mount to several different mount types.
