Its 48 mm clear aperture accommodates full-frame sensors without vignetting, and the 7.5°\/s rotation speed allows you to re-orient your camera 180° in under 30 seconds. Control is managed via a single USB-C cable, connecting directly to ASIAIR or ASCOM-based systems for full software integration.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eMotorized Framing with 0.02° Step Resolution\u003c\/h3\u003e\n\u003cp\u003eAchieve exact composition without touching your imaging train. The ZWO CAA's motorized control eliminates the flexure and shifted alignment that occurs with manual rotators. With a step resolution of 0.02° and an overall accuracy of less than 0.1°, you can precisely align guide stars, frame complex nebulae like the Horsehead (Barnard 33) and Flame (NGC 2024) in a single shot, or set up perfect mosaic sequences in your automation software.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e16.5mm Backfocus and 48mm Full-Frame Aperture\u003c\/h3\u003e\n\u003cp\u003eEngineered for modern imaging systems, the CAA inserts into your optical path with a minimal 16.5 mm profile. Its broad 48 mm clear aperture prevents vignetting on sensors up to full-frame format.
