Deep Space GatewayUnmatched Clarity for Astrophotography
The Celestron 14" Schmidt-Cassegrain Optical Tube Assembly delivers an unparalleled observational experience with over three times the light-gathering capacity of standard 8-inch telescopes. Built with StarBright XLT optical coatings and a durable aluminum optical tube, this flagship observatory-grade instrument provides breathtaking visual contrast and razor-sharp clarity for serious astronomical research and deep-sky imaging.
Observatory Grade OpticsAdvanced Engineering for Astrophotographers
Designed for demanding astronomers and astrophotographers, the Celestron 14" Schmidt-Cassegrain Optical Tube Assembly combines high-focal-length performance with innovative design features. Featuring an impressive 3910mm focal length at f/11, this Schmidt-Cassegrain optical tube allows observers to resolve fine planetary features on Jupiter and Mars or capture intricate deep-sky nebulosity. With integrated Fastar technology, users can convert the optical assembly into a lightning-fast f/2 system for vastly reduced exposure times. Combined with high-transmission water white glass and precise multi-layer coatings, the Celestron C14-AF XLT provides exceptional star resolution and maximum visual brightness across all targets.

Frequently Asked QuestionsEverything you need to know
What mount is required for the Celestron 14" Schmidt-Cassegrain Optical Tube Assembly?
Due to its 46 lb weight and long focal length, the Celestron 14" Schmidt-Cassegrain Optical Tube Assembly requires a heavy-duty observatory-class computerized equatorial mount equipped with a CGE/Losmandy-style dovetail saddle.
What is Fastar technology on the Celestron 14" Schmidt-Cassegrain Optical Tube Assembly?
Fastar technology allows you to remove the secondary mirror of the Celestron 14" Schmidt-Cassegrain Optical Tube Assembly and attach a field-flattening lens camera assembly, converting the system to an f/2 optical path for exposures up to 25 times faster.
What accessories come included with the Celestron 14" Schmidt-Cassegrain Optical Tube Assembly?
The Celestron 14" Schmidt-Cassegrain Optical Tube Assembly comes with a 40mm eyepiece (98x magnification), a 9x50 optical finderscope, a 2" star diagonal with a 1.25" adapter, a 2" visual back, and a CGE-style dovetail rail.
How do StarBright XLT coatings improve the performance of the Celestron 14" Schmidt-Cassegrain Optical Tube Assembly?
StarBright XLT coatings utilize multi-layer anti-reflective coatings and high-transmission water white glass to achieve up to 97.4% light transmission, producing brighter deep-space imagery and higher visual contrast.
