235 mm Schmidt-Cassegrain optical tube with StarBright XLT coatings and Fastar compatibility. Lightweight, compact, and highly versatile.
CELESTRON C9.25 OTA (CGE DOVETAIL)
DESCRIPTION
The Celestron C9.25 OTA is a compact yet powerful optical tube featuring a 235 mm aperture and 2350 mm focal length at f/10. Its Schmidt-Cassegrain design includes StarBright XLT coatings, enhancing light transmission and contrast for both planetary and deep sky observation.
The tube is Fastar-compatible, allowing you to remove the secondary mirror and mount a camera at f/2 focus (with an optional lens assembly). This enables extremely short exposures for deep-sky imaging.
Constructed from aluminum, it measures just 559 mm and weighs about 9 kg, making it highly portable. Supplied with a CGE dovetail bar, 6x30 finderscope, 25 mm eyepiece, 1.25" diagonal, and visual back.
INCLUDED ACCESSORIES
25 mm eyepiece (94x magnification)
