TS 110 mm F6 F660 mm APO Doublet Refractor
With its fast focal ratio of f/6, the APO 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 correctors 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 APO 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.

Astrophotography with the TS 110mm f/6 APO
The fast apo is very well suited for astrophotography. The robust 2.7" RAP focuser supports even heavy cameras, offers 360° rotation and has a micro-reduction for precise focusing. We highly recommend the following correctors:

WiflatT2 - 1.0x corrector
The corrector is simply plugged into the 2" socket and is well suited for cameras up to APS-C format. The working distance is 55mm from the T2 thread.

• TSFLAT25G2 - 1.0x Full Format Corrector

The professional corrector is designed for full format. For connection to the APO, the M74-TSFLAT25 (M68x1 adapter) transition adapter is required. This allows you to screw the corrector directly to the focuser.

For the correct working distance (55 mm from the M48 thread) you still need a 5mm M68x1 extension sleeve # TSVM685.

TSRED379 - 0.79x focal length reduction
To all astrophotographers for whom f/6 is not fast enough, we offer a focal length reduction with field correction. The focal ratio improves to f/4.74. For the connection to the APO you need the transition adapter M74-TSFLAT25. This allows you to screw the corrector directly to the focuser.

To achieve the correct working distance of 55 mm from the M48 thread, you still need 2x M48 tuning rings with 1mm thickness # M48abstimmring1.
