Celestron EdgeHD 925

1. EdgeHD Optical Design: The Celestron EdgeHD 925 features an advanced aplanatic, flat-field Schmidt-Cassegrain optical design. This specialized catadioptric construction delivers diffraction-limited images across the entire field of view, eliminating optical aberrations like coma and field curvature that are common in standard Schmidt-Cassegrain telescopes. This results in stunningly sharp, pinpoint stars from the center to the very edge of your views or astrophotographs, making it ideal for both critical visual observation and high-end astrophotography.

2. Superior Light Transmission: Equipped with Celestron's proprietary StarBright XLT coatings, this telescope maximizes light transmission through the entire optical system. This multi-layer coating technology ensures exceptionally bright, clear images with enhanced contrast, allowing you to discern faint deep-sky objects and subtle planetary details alike.

3. Optimized for Astrophotography: The EdgeHD 925 is engineered with astrophotography in mind. Its flat-field optics ensure that stars remain sharp across even large camera sensors, preventing the need for additional field flatteners. The optical tube also includes integrated tube vents with 95-micron mesh filters for faster cool-down, helping the optics reach ambient temperature quickly for optimal performance.

4. Robust and Versatile Mechanics: Built with a sturdy aluminum optical tube and a long CGE/Losmandy style dovetail bar, the EdgeHD 925 provides excellent rigidity and compatibility with a wide range of equatorial mounts. Its versatility makes it suitable for both casual stargazing and advanced imaging setups, offering a high-performance platform for exploring the universe.

ABOUT THE CELESTRON EDGEHD 925

The Celestron EdgeHD 925 represents a significant advancement in compact, high-performance catadioptric telescopes, standing out from standard Schmidt-Cassegrain designs through its innovative aplanatic, flat-field optical system. This sophisticated engineering corrects not only spherical aberration but also field curvature and coma, providing a truly flat focal plane and razor-sharp star images right to the very edge of the field of view. This makes the EdgeHD 925 an exceptional choice for serious astrophotographers seeking pinpoint stars across large camera sensors, as well as discerning visual observers desiring crystal-clear views. Its 9.25-inch aperture gathers ample light for both planetary detail and deep-sky objects, while the robust aluminum construction ensures durability and thermal stability. The integrated tube vents aid in rapid thermal equilibrium, enhancing image quality during observing sessions. The EdgeHD 925 combines portability with powerful optical performance, making it a versatile instrument for a wide array of astronomical pursuits.
