TS-PHOTON 203/800 mm Advanced Newtonian - Ideal for Astrophotography:
This Astrograph offers you pure light gathering ability due to the aperture ratio of 1:4 and therefore much shorter exposure times. With a weight of about 8.4 kg and a length of only 730cm, the Photon Newtonian is also a easily transportable for ventures to dark sky locations.
This Rich-Field-Newton is best mounted on a good astronomical mount capable of its payload and of course tracking options are a must for deep sky astrophotography.

- Bright parabolic optics with excellent contrast and very good sharpness for planetary observation and deep sky observation.
- High-quality 2" Crayford focuser with 1:10 micro reduction for 2" and 1.25" accessories.
- Focal point position ideal for DSLR and other cameras.
- All common 1.25" and 2" eyepieces can be used without any problems.
- Brighter image through forced 94% mirroring on the main and secondary mirrors.
