  4. Celestron CGEM II 800 RASA 8" Telescope

    $3,049.00
    • Flat field free of optical aberrations like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor.
    • 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.
    • NEW Ultra-Stable Focus System – six precision sealed ball bearings virtually eliminate image shift.
    • Internal filter mount – seamlessly accommodates a Light Pollution Imaging Filter into the optical path.
    • Performs over a wider spectral range than most telescopes, from 390 - 800 nm, so more of the light passing through the astrograph is in sharp focus.
    • The CGEM II, with its 40 lbs load capacity, is the latest update to the venerable CGEM mount and provides a sturdy and rigid platform for the fully-loaded RASA 8.
    • The drive system, consisting of low cog DC Servo motors with integrated optical encoders, steel worm gears supported by precision sealed bearings, and brass worm wheels, ensures smooth and accurate slewing and tracking.
    • Proven NexStar+ computerized telescope control technology supports functions to address imagers’ needs, such as All-Star Polar Alignment, Permanent Periodic Error Correction (PPEC), and adjustable tracking through meridian.
  5. Celestron CGX 800 RASA 8" Telescope

    $3,699.00
    • Flat field free of optical aberrations like field curvature, coma, astigmatism and chromatic aberration across an entire APS-C sensor.
    • 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.
    • NEW Ultra-Stable Focus System – six precision sealed ball bearings virtually eliminate image shift.
    • Integrated air cooling system –12V DC MagLev fan reduces cooldown time and provides optimal air flow while filtering out dust.
    • Internal filter mount – seamlessly accommodates a Light Pollution Imaging Filter into the optical path.
    • Performs over a wider spectral range than most telescopes, from 390-800 nm, so more of the light passing through the astrograph is in sharp focus.
    • 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.
    • The drive system utilizes low cog DC Servo motors with integrated optical encoders, belt and pulley motor connection, spring-loaded steel worm gears supported by precision sealed bearings, and brass worm wheels for smooth, accurate slewing and tracking performance with little backlash.
    • 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.
    • Proven NexStar+ computerized telescope control technology supports functions to address imagers’ needs, such as All-Star Polar Alignment, Permanent Periodic Error Correction (PPEC), and adjustable tracking through meridian.
