Product Details

  • Celestron’s 11-inch EdgeHD OTA’s built-in field flattener and optic design produce sharply focused, aberration-free and coma-free flat field views, which is ideal for serious astro-imagers. The EdgeHD ensures a flat focal plane all the way across to the edge of the field-of-view for optimal imaging, yielding high definition and pinpointing stars.

    Edge HD optics help you not only capture rounder, more pleasing stars but improves its resolution and limit magnitude. When it comes to the Celestron EdgeHD series coupled with Celestron's StarBright XLT coating group on every surface, EdgeHD optics gives you maximum light across the widest visual and photographic spectrum... It's a vision you'll never forget!

    • Mirror Support Knobs- Flexible tension clutches hold the mirror in place and reduce image shift when rotating the tube around the mount.
    • Tube Vents- Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. The vents are outfitted with an integrated 95-micron mesh filter.
    • Fastar Versatility-All EdgeHD optical tubes are Fastar compatible for imaging down to f/2 with optional accessories. 
    • Brighter Star Images- Light becomes more concentrated when focused precisely. This maximizes image brightness. 
    • CGE Mount Plate- Ready for attaching to your mount and tripod of choice.
