SCA310

The SCA310 is a 310mm large-aperture Cassegrain reflector featuring a fast f/3.8 focal ratio, powerful light-gathering capability, and a wide imaging field for deep-sky astrophotography. This purpose-built 310 mm f/3.8 Cassegrain astrograph delivers high signal efficiency, wide corrected fields, and mechanical stability for long-duration imaging. The SCA310 is specially optimized for medium format and fully covers the full-frame sensors, providing nearly 100% illumination and a flat image field. The carbon fiber tube is lightweight and robust, effectively reducing overall weight while providing excellent structural stability and temperature adaptability, preventing focus shift caused by thermal expansion and contraction.
