  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

  2. TS 8" f/12 Cassegrain telescope with fused Quartz mirror and only 33% obstruction - the ideal alternative to a Schmidt-Cassegrain

    • 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

  3. This new, All-In-One design marries high quality components of a telecentric barlow, adapters, snouts and Daystar hydrogen alpha filter into one simple assembly.

  5. Explore highly magnetized and powerful excitations in the bright Magnesium I (b2) line. For use on refractors of F/4 - F/8 focal ratio refractors. This latest and likely the last wavelength offered for Quark reveals a whole new area of highly magnetized high energy in the bright 5172.8Å wavelength. The eye is most sensitive at this wavelength so the image is significantly brighter than calcium. Views show both plage and dark mottling of chromospheric network.

  6. Skyliner 300/1500 Flextube Dobsonian Newtonian telescope with 300mm aperture and 1500mm focal length (f/5). Wooden base, collapsible tube and accessories included.
