Celestron EdgeHD 9.25-Inch SCT Optical Tube Assembly (Open Box)
Condition: Open Box
Condition Details: Fully functional item with opened or replaced packaging; essential accessories included.
The Celestron EdgeHD 9.25" Schmidt-Cassegrain Optical Tube Assembly is a high-performance telescope designed for both advanced visual observing and astrophotography. Featuring an aplanatic, flat-field optical design, it delivers sharp, aberration-free images from edge to edge—ideal for capturing detailed views of the Moon, planets, and deep-sky objects.
True Flat-Field Optics
Unlike standard Schmidt-Cassegrain designs, EdgeHD optics produce an astrograph-quality flat focal plane, ensuring pinpoint stars across large camera sensors and the entire visual field.
Exceptional Image Quality
With a 9.25-inch aperture and a 2350mm focal length, this OTA offers excellent resolution and light-gathering power. StarBright XLT optical coatings maximize light transmission for brighter, higher-contrast views across visual and photographic wavelengths.
Optimized for Imaging
Designed for versatility, the EdgeHD supports imaging at its native f/10, with optional reducers for wider fields of view, Barlow lenses for planetary imaging, and Fastar compatibility for ultra-fast f/2 imaging when paired with third-party accessories.
Advanced Mechanical Design
Mirror clutches minimize image shift during long exposures, while rear cooling vents with integrated filters help the optics reach thermal equilibrium faster—critical for sharp, stable imaging sessions.
Individually Tested for Quality
Each EdgeHD OTA is factory tested using artificial stars and imaging systems to ensure it meets Celestron’s strict optical and mechanical standards.
A powerful and flexible platform for serious astronomy and astrophotography, the Celestron EdgeHD 9.25" OTA delivers professional-level optical performance in a robust, imaging-ready design.
