Celestron C14 XLT Schmidt-Cassegrain OTA (CGE dovetail)
Celestron C14 XLT Schmidt-Cassegrain OTA (CGE dovetail) 14" Schmidt-Cassegrain optical tube, 3910 mm f/11, CGE (Losmandy-style) dovetail bar.
Celestron's classic Schmidt-Cassegrain packs a long focal length into a short, rugged aluminium tube. StarBright XLT coatings on every optical surface maximise light transmission and contrast, so it is equally at home on the Moon and planets, small galaxies and planetary nebulae. Fastar compatible: the secondary mirror can be removed for third-party f/2 imaging systems. Pair it with the Celestron 0.63× reducer/corrector for a faster, wider field.
