    • Flat-field free of optical aberrations like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor.
    • Ultra-Stable Focus System – precision linear ball bearing virtually eliminates image shift.
    • Internal filter mount – seamlessly accommodates a Light Pollution Imaging Filter into the optical path.
    • The CGX, with its 55 lb load capacity, is Celestron’s most innovative, state-of-the art, computerized equatorial mount to date, and provides a very sturdy and rigid platform for the fully-loaded RASA 8.
    • Fully remote imaging capable, with optical limit switches, home sensors, through-mount cabling, and hard stops.
    • Included Celestron PWI software allows direct computer control via USB 2.0 connection.

    Purely designed for imaging, the 8” RASA cannot be used visually.

     Built for Today’s Latest Cameras

    Unlike the larger RASAs that work with DSLR and large CCD cameras, the 8” model was designed with color astronomical CMOS cameras, smaller CCD cameras, and mirrorless cameras in mind. The telescope does not work with standard DSLR cameras.

    Solar Warning
    • Never look directly at the Sun with the naked eye or with an optic (unless you have the proper solar filter). Permanent and irreversible eye damage may result.
    • Never use your optic to project an image of the Sun onto any surface. Internal heat build-up can damage the optic and any accessories attached to it.
    • Never leave your optic unsupervised. Make sure an adult who is familiar with the correct operating procedures is with your optic at all times, especially when children are present.
