TS-Optics Photon 8" F/4 Newtonian

TS-Optics Photon 8" F/4 Newtonian

Astrophotography is easy with this compact Newtonian from the TS-Optics Photon series. Due to the fast focal ratio of f/4, this astrograph provides pure speed and therefore short exposure times. 

Features

• Fast parabolic optics with outstanding contrast and very good sharpness for planetary and deep-sky observation.
• High-quality 2" MONORAIL focuser with 1:10 dual speed for 2" and 1.25" accessories.
• All popular 1.25" and 2" eyepieces can be used.
• Brighter image through enhanced 94% reflectivity of primary and secondary mirror.
  
• The active ventilation for the primary mirror provides for a clearly faster cooling down.
