Description
TS-PHOTON 203/800mm Advanced Newtonian for astrophotography and observing
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.
