  3. Celestron 9.25" EdgeHD optical tube, CGE/Losmandy dovetail

    $2,999.00
    The EdgeHD high definition flat field optics of this Celestron 9.25" EdgeHD optical tube give you true astrographic-quality 9.25" optics with a definite edge over other reduced coma optical systems . . .
  4. Celestron 8” ROWE-ACKERMANN SCHMIDT ASTROGRAPH (RASA 8)

    $2,079.00
    • 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.
    • CGE dovetail mounting rail.
    • 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.
