♦ Fast parabolic optics with outstanding contrast and very good sharpness for planetary observations.
♦ High-quality 2" Crayford focuser with 1:10 dual speed for 2" and 1.25" accessories.
♦ Focus position perfect for DSLR and other cameras.
♦ All popular 1.25" and 2" eyepieces can be used without problems.
♦ Brighter image through enhanced 94% reflectivity of primary and secondary mirror.
♦ Motor focus can be retrofitted at any time.
♦ A 0.5 mm thin stainless steel spider provides stability. Astrophotographers will envy you for the delicate and sharp spikes around bright stars.
♦ The active ventilation for the primary mirror provides for a clearly faster cooling down.
♦ Adjustable primary mirror cell and secondary cell completely made of metal.
Astrophotography is easy for you with this compact Newtonian from the TS-PHOTON series. Due to the aperture ratio of f/4, this astrograph provides pure speed and therefore short exposure times. Of course, we also offer the matching coma corrector TS SUPERFLAT. Thus this PHOTON Newtonian becomes a very good astrograph.
Immerse yourself in the world of deep-sky observing with the PHOTON 8" f/4. The large aperture and the enhanced reflectivity of 94% offer unforgettable observations beyond the solar system. Watch exciting details, like spiral arms of galaxies or fine structures in planetary nebulae.
Purely visual observers can also use an altazimuth mount, but we would recommend an equatorial mount with GoTo drive to fully realise the full potential this fantastic optical instrument.
