TS-Photon 114 mm f/4 Advanced Newtonian with Carbon Tube
The compact Newtonian with the carbon tube is a compact travel telescope for observation and astrophotography. The telescope fits in any hand luggage.

The advantages of the 4.5" TS Photon Newton:
Fast, high-quality parabolic primary mirror for very good contrast and sharpness
Improved 1.25" Crayford with T2 connection and reduction
Massive secondary mirror spider vanes, twisting is no longer possible, which facilitates collimation
A compact coma corrector for the Newtonian is under development
Brighter image due to forced mirroring on primary and secondary mirror
Primary mirror cell and secondary mirror cell are adjustable and of course made of metal
