  1. The 8" Ritchey-Chrétien is the perfect telescope for astrophotography, but it is also suitable for visual observation.

    • ♦ Aperture 8" / 203 mm - focal length 1624 mm - focal ratio f/8
    • ♦ Hyperbolic primary and secondary mirror for very high sharpness on the optical axis and a large well-corrected field for astrophotography
    • ♦ Both mirrors made of fused silica for stable focus position
    • ♦ 99% high-reflectivy coating on main and secondary mirror for an even brighter image and more contrast - special service from TS
    • ♦ Quicker cooling down thanks to open construction and primary mirror ventilation
    • ♦ Two Vixen style dovetail bars supplied - ideal for accessories like guiding scopes or a piggyback camera mount
    • ♦ High-quality 2" dual speed MONORAIL focuser with 2" / 1.25" reduction adapter - motor focuser optionally available
    • ♦ RC correctors for larger sensors from APS-C upwards are optionally available

    • 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.

    • Experience our best optical performance with EdgeHD’s aplanatic, flat field Schmidt-Cassegrain optics for pinpoint stars all the way to the edge of today’s largest imaging sensors and widest eyepieces.
    • Aluminum optical tube with tube vents featuring an integrated 50-mesh filter allows hot air to be released from behind the primary mirror. Mirror support knobs hold the mirror in place and reduce image shift during imaging.
    • Versatile design accommodates 3 focal ratios: native f/10, f/7 with the addition of a focal reducer, or ultra-fast f/2 imaging with a removable secondary mirror and third-party accessories.
    • Celestron’s premium StarBright XLT coatings provide maximum light transmission.
    • A 9x50 finderscope, 1.25” mirror diagonal for more comfortable viewing, and 40 mm Plössl 1.25” eyepiece are all included.

    • Aperture 8" - 203 mm
    • Focal length 2436 mm
    • F-ratio f/12
    • Large illuminated image field with 45 mm diameter
    • Hyperbolic secondary mirror and parabolic primary mirror made of Quartz glass for stable focus position
    • 99% reflection on primary and secondary mirror for an even brighter image
    • Quick temperature adaption due to open design
    • Pure reflective system without Schmidt plate or meniscus lens - fully suitable for Infrared
    • Only 33 % linear obstruction - very well suited for visual astronomy
    • 2" MONORAIL focuser with micro-gear reduction and 1.25" reduction are included
    • M90 extension tubes for trouble-free focusing with almost any accessories included
    • Internal baffles for higher contrast
    • Losmandy style dovetail and Vixen/EQ5 style dovetail for trouble-free adaption to all popular mounts
    • Finder-scope shoe is also included
    • Very economically priced, compared with other classical Cassegrains
