Stunning astrophotos and extreme depth at a moderate time effort - this is what the PowerNewtonians from Teleskop Service stand for.

• Short exposure times at f/2.8 - perfect for DSLR cameras without cooling
•  Moderate exposure times when using narrowband filters
•  Very good field correction thanks to the ASA corrector/reducer
•  High mechanical stability due to the carbon tube
•  Total length of only 1100 mm, weight of 18 kg - can also be carried by affordable mounts
•  Back Focus 65 mm starting from the T2-thread - also suitable for OAG
•  Fully illuminated and corrected field for APS-C format sensors
•  The first image at left shows the very similar 10" model.
•  Made in Germany

The PHOTON Newtonian reflector with 150 mm aperture and an f-ratio of f/5 is well suited for observation and astrophotography and an ideal beginner´s telescope.

• Aperture 150 mm / Focal length 750 mm / F-ratio F5
• High-quality parabolic primary mirror with 94% reflection coating for a brighter image.
• Large secondary mirror with 63 mm diameter for a well illuminated image field for astrophotography
• Precise 2" Crayford focuser for accurate focusing and micro transmission - motorfocus optional.
• Carbon tube for more stability with better portability at the same time - Made in Germany!
• Adjustable primary and secondary mirror holder made of metal, convenient collimation marking on primary mirror
• Focus position optimized for observation with all customary eyepieces and for astrophotography with coma correctors
• Due to its short build the Newtonian is suitable for smaller mounts (Skywatcher EQ3 upwards)
• Central mark on the primary mirror for easy collimation
• Generous equipment: 6x30 finder scope, ring clamps, dovetail included
