Celestron EdgeHD 9.25" Optical Tube with CGE Dovetail
Flat-field aplanatic Schmidt-Cassegrain optics for pinpoint stars across large sensors. Designed for astrophotography and high-resolution visual observing with a ventilated aluminum tube, optimized secondary obstruction and Fastar compatibility for ultra-fast f/2 imaging.
Celestron EdgeHD 9.25" Optical Tube with CGE Dovetail
DESCRIPTION
The Celestron EdgeHD 9.25" is a flat-field Schmidt-Cassegrain telescope delivering outstanding performance for imaging and visual observation. The aplanatic optical system eliminates off-axis coma and provides a flat focal plane, ensuring sharp stars even at the edge of the field.
All optical surfaces feature StarBright XLT coatings for maximum light transmission. Mechanically, the tube includes vented rear cells with integrated filters, mirror clutches to prevent image shift during imaging, and full compatibility with Fastar accessories for wide-field f/2 astrography.
Included are a 9x50 finderscope, 2" diagonal with 1.25" adapter, and a wide-angle 23 mm Luminos eyepiece.
