DescriptionWhen you\'re seeking a high-quality, advanced telescope for celestial observation, look no further than the EdgeHD 11" Schmidt-Cassegrain Optical Tube Assembly with Starbright XLT Coatings. This innovative and sophisticated telescope is designed to deliver aberration-free, high-definition views of the universe, making it a top choice for both amateur and professional astronomers.The EdgeHD 11" is an aplanatic, flat field Schmidt-Cassegrain telescope, designed to produce sharp, clear images across a wide visual and photographic field of view. Unlike many optical designs that claim to be "astrographs", the EdgeHD 11" ensures pinpoint stars across a flat focal plane, providing true astrograph quality. This means that even when used with the flat chip sensor of a digital camera, stars will appear in focus right to the edge of the field of view.The EdgeHD 11" offers superior edge performance, creating rounder, more pleasing stars, and improving resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestron\'s StarBright XLT optical coatings on every surface, you can expect maximum light throughput across the widest visual and photographic spectrum.The telescope tube has been redesigned with mechanical features such as mirror clutches and tube vents. The mirror clutches hold the mirror in place and reduce image shift during long exposure astro-images, while the tube vents allow hot air to be released from behind the primary mirror, ensuring dust-free operation.The EdgeHD 11" is also Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third-party lens accessory for ultra-fast f/2 wide field imaging. This versatility makes the EdgeHD 11" the most adaptable imaging telescope available today.The EdgeHD 11" comes with a 23mm Luminos Series 2" Eyepiece, offering a wide 82-degree field of view. The eyepiece is fully multi-coated for crisp, sharp views and is parfocal, meaning you can switch out eyepieces during observing sessions with little or no additional focusing required. The eyepiece body is made of polished and anodized aluminum, with a rubber grip for secure handling and smooth control of the retractable eyecup.Every EdgeHD 11" that ships has been individually tested for surface quality of each optical component and with a camera and artificial star to ensure the imaging system meets our rigid quality assurance. This guarantees that the EdgeHD 11" will perform in the field and deliver high-quality astroimages.In summary, the EdgeHD 11" Schmidt-Cassegrain Optical Tube Assembly with Starbright XLT Coatings is a durable, high-quality telescope that offers advanced features and sophisticated design for an exceptional stargazing experience.FeaturesExperience our best optical performance with EdgeHD\'s aplanatic, flat field Schmidt-Cassegrain optics for pinpoint stars all the way to the edge of today\'s largest imaging sensors and widest eyepiecesAluminum optical tube with tube vents featuring an integrated 50-mesh filter allows hot air to be released from behind the primary mirror.
