Celestron S 203/400 RASA 800 CGX GoTo

Description

Heavy-duty computerized imaging control supports the Celestron S 203/400 RASA 800 CGX GoTo, an 8-inch Rowe-Ackermann Schmidt Astrograph with a 400 mm focal length and listed f/2 optical ratio. Its CGX German equatorial mount provides a 55-pound payload capacity, belt-driven movement, dual dovetail saddle, motorized tracking, NexStar+ control, and spring-loaded worm gear support, while the RASA tube includes StarBright XLT coatings, precision focusing, cooling, filter support, and camera adapters.

The RASA 8 is designed for dedicated electronic imaging rather than visual observation, so the complete system requires a compatible camera and imaging workflow. The optical tube supports color astronomical CMOS cameras, smaller CCD cameras, and compatible mirrorless cameras, while the included C-thread and M42-style camera adapters, fan battery pack, and CGE rail support the specified imaging configuration without adding unsupported visual eyepiece claims.
