Description
Custom ACF integration begins with the Meade ACF-SC 152/1524 UHTC OTA, a standalone 152 mm Advanced Coma-Free 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, 8×50 finder, 26 mm eyepiece, diagonal, Vixen dovetail, visual back, and aluminum housing provide a complete optical starting point for a separately selected mount.
The OTA is supplied without an equatorial or alt-azimuth mount, tripod, counterweights, or electronic tracking, so the final system must be built around compatible payload and dovetail requirements. The configuration supports planetary, lunar, deep-sky, and supported astrophotography applications, while focus spacing, guiding, camera compatibility, thermal behavior, and tracking performance depend on the selected mount and accessories.
Key Features of Meade ACF-SC 152/1524 UHTC OTA
This standalone Advanced Coma-Free optical tube combines a 152 mm aperture with a 1524 mm focal length, UHTC coatings, hyperbolic secondary, aspheric corrector, internal focusing, 8×50 finder, 26 mm eyepiece, diagonal, visual back, and Vixen-style mounting rail.
