Ultimate Astroimaging PerformanceDiscover Unmatched Deep-Sky Clarity
The Celestron 14" Edge HD Optical Tube Assembly (OTA) is a premier aplanatic flat-field Schmidt-Cassegrain telescope designed to deliver astrograph-quality images across a wide visual and photographic field of view. Engineered with premium StarBright XLT optical coatings, this telescope eliminates spherical aberrations and off-axis star coma for razor-sharp observational astrophotography.
Astrograph-Quality Precision OpticsEngineered For Large Sensor Cameras
Designed for serious astrophotographers and astronomical observatories, the Celestron 14" Edge HD Optical Tube Assembly (OTA) produces a focal plane more than three times flatter than standard Schmidt-Cassegrain telescopes, ensuring pinpoint star clarity to the very edge of full-frame CCD and CMOS camera sensors. Featuring a rugged aluminum optical tube equipped with cooling tube vents, integrated 50-mesh dust filters, and flexible tension mirror clutches, this high-performance Celestron optical tube assembly effectively minimizes image shift during long-exposure imaging. Furthermore, its versatile Fastar technology compatibility allows astronomers to shoot at native f/11, f/7 with a focal reducer, or an ultra-fast f/2 wide-field setup.

Frequently Asked QuestionsEverything you need to know
What type of camera sensors are compatible with the Celestron 14" Edge HD Optical Tube Assembly (OTA)?
The Celestron 14" Edge HD Optical Tube Assembly (OTA) is specifically engineered with an aplanatic flat-field optical design that produces pinpoint stars across full-frame CCD and CMOS camera sensors without off-axis coma or field curvature.
How does Fastar technology work on the Celestron 14" Edge HD Optical Tube Assembly (OTA)?
Fastar technology allows you to remove the secondary mirror on the Celestron 14" Edge HD Optical Tube Assembly (OTA) and replace it with a third-party lens assembly, converting the native f/11 system into an ultra-fast f/2 wide-field astroimaging setup.
What mounting rail comes attached to the Celestron 14" Edge HD Optical Tube Assembly (OTA)?
The Celestron 14" Edge HD Optical Tube Assembly (OTA) comes equipped with a wide CGE dovetail bar, making it compatible with heavy-duty equatorial mounts such as the Celestron CGX-L.
What is the purpose of the mirror clutches on the Celestron 14" Edge HD Optical Tube Assembly (OTA)?
The flexible tension mirror clutches hold the primary mirror firmly in place without applying excessive pressure, keeping images centered and eliminating mirror shift during long-exposure astrophotography.
