Telescope-Catadioptric Telescopes-Celestron EdgeHD 14 OTA – 14″ f/11 Aplanatic HD OTA – Cosmetic Blemish

The Celestron EdgeHD 14. Where Innovation Meets Optics!

Known for their industry leading optics, Celestron has taken the Schmidt Cassegrain optical design up a notch: delivering an aplanatic, flat field astrograph perfect for any astro-enthusiast! The EdgeHD series has been designed specifically with astrophotography in mind—including a set of corrector lenses near the rear of the telescope to enhance photographic performance. The resulting 5 internal optical elements produce an inherent flat field and images free from coma and spherical aberrations. While excellent for astrophotography applications, this Celestron EdgeHD allows you the opportunity to enjoy stunning, bright views as well! No matter if you choose to utilize this EdgeHD 14 for astrophotography or for visual astronomy, you can expect one thing: quality.

In addition to the 5 optical components delivering exceptional resolving power, the body of the optical tube features mechanical upgrades such as mirror clutches and tube vents to maximize this telescope’s performance. Celestron doesn’t stop there! The patented StarBright XLT coatings help increase light transmission even further, producing vibrant sights and astrophotos brimming with detail. When it comes to choosing what to observe or what to image, plenty of options ensue. The 3910 mm focal length is ideal for deep dives into nebulous regions of the night sky, while also allowing the opportunity to get to know the planets. This EdgeHD offers 14” of aperture. That’s 1.62x the light gathering power of the EdgeHD 11. Fitted with a removable secondary mirror, add the Starizona Hyperstar for wildly fast f/2 imaging! Wanting to enhance your EdgeHD experience even more? Celestron offers an ecosystem of optional accessories, such as a Focal Reducer and Dew Rings, and comes equipped with included accessories like a star diagonal and 23 mm Luminos eyepiece. This feature-packed Celestron EdgeHD 14 gives you the power to take your astronomy journey to new heights.

Commitment to Quality: Celestron EdgeHD Technology

Understanding the needs of astrophotographers, the engineers at Celestron sought to develop a new astrograph that would deliver images free from comatic aberration and field curvature. The solution? The development of their EdgeHD series! These super-charged Schmidt Cassegrain telescopes include a set of corrector lenses made of premium Schott glass in the rear baffle tube. These powerful lenses, along with the spherical primary mirror, spherical secondary mirror, and aspherical front corrector lens work together to virtually eradicate any aberrations. Compared to classic Schmidt Cassegrains, EdgeHD optics feature a focal plane that’s more than 3x flatter. This ensures stars all the way to the corners of the 42 mm image circle are sharp and round. While other optical designs are advertised as astrographs, the true astrograph quality of the EdgeHD series provides pinpoint stars across a flat camera chip, not just pinpoint stars across a curved focal plane. This geometric harmony of a flat camera chip and flat focal plane makes the EdgeHD OTAs optimal for astrophotography applications. In addition to producing round stars, this superior edge performance helps enhance the limiting magnitude and resolution when compared to telescopes of equal aperture. To put this into perspective, poor edge performance blurs the starlight so much that it’s difficult to detect dimmer stars with your eye or camera sensor. This is a stark contrast to the clarity delivered by EdgeHD technology as even faint galaxies along the edges of the field of view can be easily resolved. Not only is field curvature well corrected for, but off-axis comatic aberration is also kept in check! This aberration presents itself as unfocused, comet-like stars near the corners of the image, though with the embedded sub-aperture lenses, the stars come into focus across the entire field of view. Ensuring each telescope is of the utmost excellence, Celestron performs a final acceptance test on every EdgeHD unit prior to shipment. The surface quality of the optics is thoroughly inspected and the photographic performance is assessed with a camera and artificial star. Thanks to Celestron’s top-tier quality standards, you can enjoy outstanding performance during every astronomy session.
