Celestron C14 OTA - CGE Dovetail

14" Schmidt-Cassegrain: 0.33 Arc Second Dawes Limit

The C14's optical power is defined by its immense 355.5mm primary mirror, which provides the light-gathering ability necessary to resolve fine details that smaller instruments cannot. This aperture allows the C14 to reach a Dawes resolution of 0.33 arc seconds, enabling you to clearly see Cassini's Division in Saturn's rings and resolve detail on the surface of Mars. The long 3910mm focal length is ideal for high-magnification views, and the included 40mm eyepiece provides an initial magnification of 98x for locating and centering objects.

StarBright XLT Coatings: Maximizing Contrast and Transmission

To ensure maximum light reaches your eye or camera sensor, the C14 features Celestron's premier StarBright XLT optical coatings. This advanced system uses enhanced multi-layer mirror coatings and multi-layer anti-reflective coatings on the corrector lens to dramatically increase light transmission and contrast. The result is visibly brighter images, deeper views into faint nebulae, and shorter exposure times for astrophotography. While all Schmidt-Cassegrains have a central obstruction, the C14's is held to just 10% by area, preserving the high-contrast views the design is known for.

Imaging Versatility: From Native f/11 to Hyper-Fast f/2

The C14 is a formidable imaging platform with two distinct personalities. At its native f/11 focal ratio, it excels at high-resolution planetary, lunar, and small galaxy imaging, leveraging its long focal length to achieve large image scales. For deep-sky imagers, the OTA is Fastar compatible, allowing the secondary mirror to be replaced with a third-party lens assembly. This converts the C14 into an incredibly fast f/2 astrograph, reducing exposure times by a factor of 25 and enabling the capture of vast nebulae in a fraction of the time.

Observatory-Class Build: 46 lb OTA with CGE Dovetail

Engineered for stability and performance, the C14's aluminum optical tube weighs 46 lbs and measures 787mm (31") in length. It comes equipped with a heavy-duty CGE-style dovetail bar for secure attachment to observatory-grade mounts. The package includes essential accessories to get you started, including a 9x50 finderscope for easy object location and a 2" star diagonal with a 1.25" adapter, providing flexibility for a wide range of eyepieces and accessories.

Celestron C14 vs. C11: The Leap from 11" to 14" Aperture

For observers deciding between Celestron's large SCTs, the choice often comes down to the C14 and its smaller sibling, the C11. The C11 is a superb instrument that is lighter and can be carried by less massive mounts. However, the C14 represents a significant step up in capability.

• Light Gathering: The jump from an 11-inch to a 14-inch primary mirror provides a substantial increase in light-gathering power. This directly translates to brighter images, the ability to see fainter stars, and resolving more detail in the spiral arms of galaxies and the faint outer regions of nebulae.
• Resolution: The C14's larger aperture gives it a superior resolving power, allowing for higher-magnification views of planets and the ability to split tighter double stars than the C11. For imagers, this means a higher level of achievable detail.
• Mount Requirements: The C14's 46 lb weight demands a robust mount like a CGX-L or equivalent. The C11 is less demanding, making it a more portable option. The C14 is the choice for a permanent or semi-permanent setup where ultimate performance is the goal.
