Celestron EdgeHD 800 SCT OTA

The unparalleled capabilities of the Celestron EdgeHD 800 SCT OTA, a stellar optical tube assembly designed for astrophotography enthusiasts. As part of the EdgeHD series by Celestron, this telescope boasts a 3x flatter focal plane compared to standard Schmidt-Cassegrains, ensuring pinpoint stars across the widest eyepieces and imaging sensors. The EdgeHD features a specialized aplanatic, flat-field Schmidt-Cassegrain design, delivering aberration-free images across an expansive visual and photographic field of view.

True Astrograph Quality

Many optics claiming to be “astrographs” only produce pinpoint stars across a curved focal plane. EdgeHD optics, however, offer a focal plane more than three times flatter than standard Schmidt-Cassegrains, providing visibly sharp stars even on the largest CCD chips.

Improved Performance

Enhanced edge performance not only results in rounder, more pleasing stars but also boosts resolution and limiting magnitude compared to telescopes of similar aperture. With Celestron’s StarBright XLT optical coatings, EdgeHD optics maximize light throughput across the widest visual and photographic spectrum.

Mechanical Features:

Complementing the optimized optical design, the telescope tube incorporates key mechanical features to maximize performance:

• Mirror Clutches: Flexible tension clutches ensure stability during long-exposure astro-images, reducing image shift.
• Tube Vents: Cooling vents release hot air from behind the primary mirror, each with an integrated 50-mesh filter to allow warm air out without permitting dust in.
• Fastar Versatility: EdgeHD stands out as the most versatile imaging telescope, accommodating various imaging scenarios, from capturing the smallest deep-sky objects to high-resolution planetary imaging. Fastar compatibility allows seamless integration with third-party lens accessories for ultra-fast f/2 wide field imaging.

Quality Assurance through Rigorous Testing

Each EdgeHD undergoes thorough testing before shipping, ensuring not just the surface quality of each optical component but also a comprehensive evaluation with a camera and artificial star. This stringent quality assurance process, culminating in a final acceptance test, guarantees that the EdgeHD will not only meet but exceed expectations in the field, delivering stellar performance and high-quality astroimages.
