TS-PHOTON 12" f/5 Newtonian telescope OTA. This 12" Newtonian from the Photon series is a true all-rounder and one of the most powerful telescopes in its price range.
With its versatile focal ratio of f/5, this Newtonian provides all the prerequisites for lunar and planetary observations. The optimized secondary mirror with 80mm diameter (minor axis) is designed as well for deep-sky observation and also for astrophotography. The obstruction of only 26% and the extremely precise primary mirror allows magnifications up to approximately 750% at suitable quality seeing conditions. The limit of the resolution is in effect only the blurring from the earth´s atmosphere itself.
The 12" f/5 PHOTON Newton is a large OTA and therefore needs a stronger mount, for example the SXP2 from Vixen, EQ8 from Skywatcher or the CGX from Celestron.
Moderate aperture ratio for short exposure times in astrophotography.
Very good sharpness on moon and planets
High backfocus allows using standard coma correctors and cameras
High-quality primary mirror made of optical BK7 glass with enhanced 94% reflection for a bright clear image.
Central mark at the primary mirror for easy precise collimation.
Stable 1:10 dual speed 2" Crayford focuser with 1.25" reduction
Motor focus can be retrofitted at any time.
Faster cooling down for observing and photographing earlier due to the fan mounted on the primary mirror
Steel tube and metal mirror cells for optimal collimation stability
The precise 2" Crayford focuser with 1:10 micro transmission: This Newtonian telescope includes a 2" Crayford focuser with integrated 1:10 dual speed transmission. This focuser works very accurate even with heavy accessories like astro cameras. With a bit of experience, you can achieve a focusing accuracy of around 0.08 mm which is sufficient even for sensors of very high resolution.
High-quality primary mirror with f/5 and 94% reflectivity: This Newtonian shows its full potential at observation and astrophotography due to a high-quality primary mirror made of optical BK7 glass, free from internal stress. The parabolic mirror has a 94% reflectivity coating, thus offering a brighter and more contrasting image. You can instantaneously notice the difference when comparing to a standard coating.
