Description
Advanced Coma-Free optics define the Meade ACF-SC 152/1524 LX85 OTA, a standalone 152 mm catadioptric optical tube with a 1524 mm focal length and listed f/10 optical ratio. Its UHTC coatings, hyperbolic secondary, aspheric corrector, internal zero-shift focusing system, 8×50 finder, 26 mm eyepiece, 1.25-inch diagonal, Vixen dovetail, and padded transport case support a custom visual or imaging telescope configuration.
The optical tube is supplied without a complete mount, tripod, counterweights, or electronic tracking system, so final performance depends on the selected compatible platform. The ACF design is intended for planetary and deep-sky observation, while the internal baffle focus mechanism, Vixen rail, 8×50 finder, and included visual accessories provide the main integration points for a separate telescope system.
