Product description

TS 110 mm F6 F660 mm ED Doublet Refractor

With its fast focal ratio of f/6, the ED is faster than simple EDs, which are usually f/7 to f/9. In order to still achieve good chromatic correction, the FPL51 special glass was supplemented by another special glass (lanthanum glass). This achieves a correction equivalent to a normal f/7 to f/8 ED refractor. The high speed also offers advantages for astrophotography, an object can be exposed in just one night. Suitable 1.0x flatteners can be found in the accessories section.

All lens surfaces are coated with a multi-coating for maximum light transmission. Baffles inside the optical tube and in the focuser prevent reflections and ensure sharp, high-contrast images.

The TS 110 mm ED has a high-quality 2.7" gear-driven focuser with ball bearings. This guarantees sensitive and accurate focusing even with heavy accessories. The focuser accepts 2" and 1.25" accessories. You can also use 2" diagonals and common correctors.

The comprehensive features are complemented by sturdy CNC tube rings and a sturdy transport and storage case.
