  • The PHOTON Newtonian reflector with 254 mm aperture and the aperture ratio f/4 is a fast astrograph for astrophotography and a powerful wide-field telescope

    TS-PHOTON 10" F4 Advanced Newtonian Telescope with Metal Tube  [EN]

  • ♦ Aperture 254 mm / focal length 1016 mm / focal ratio F4
  • ♦ High-quality parabolic primary mirror with 94% reflectivity for a brighter image.
  • ♦ Large secondary mirror for a well-illuminated image - cameras with full-frame size sensors also suitable.
  • ♦ Precise 2" MONORAIL focuser for more stability than with conventional Crayford focusers.
  • ♦ Adjustable primary and secondary mirror cells made of metal, useful collimation aid on the primary mirror.
  • ♦ Focus position ready for observing with all popular eyepieces and for astrophotography.
  • ♦ Extensive scope of delivery: 8x50 finder, tube rings, 2" extension tube for observing, dovetail bar.
  • ♦ Start quicker with photography and observing due to fan for the primary mirror.

TS-PHOTON 254/1016mm Advanced Newtonian for astrophotography and observing
Astrophotography is easy for you with this 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 10" 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.

General information and features of the TS-PHOTON Newtonian telescopes:

♦ Fast parabolic optics with outstanding contrast and very good sharpness for planetary observations.
♦ High-quality 2" MONORAIL 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.

More joy in astrophotography through optimal field correction - advisory service from Teleskop-Service
Only a good coma corrector turns this Newtonian into a true astrograph. Our recommendation is the TSGPU corrector which is perfect for this telescope. it will offer you highest sharpness in the entire field, only with the TSGPU (see accessory recommendations) this Newtonian turns into a true astrograph.

The working distance from the M48 thread is 55 mm. With a T-ring, you are automatically at the right distance for astrophotography with DSLR cameras. We can offer you suitable adaptions for your astro camera anytime within the context of our consultation.
