Product description

TS 110 mm f/7 ED refractor with 2.5" RAP focuser - for observation and photography

The TS 110 ED offers higher resolution and 16% more light than a 102 mm refractor at a similar weight and size. The refractor can still be carried well by mounts in the EQ5 class, even for astrophotography. The 110-mm ED is a well transportable telescope for astrophotography and also for observing.

The sturdy 2.5" RAP focuser opens up new possibilities

A special feature is the modern focuser. The focuser provides better illumination than 2" focusers. The focuser is an asset for observing and also for astrophotography.

  • 360° rotation for selecting the correct field of view
  • Dual speed for precise adjustment of sharpness
  • Adjustment by a toothed rail - decoupled from the bearing
  • Motorized focus systems can be connected
  • Correctors can be screwed directly to the auxiliary thread
  • 2" and 1.25" adapters with ring clamps are included.

Astrophotography with the TS 110 mm f/7 ED refractor

The ED lens provides good imaging for astrophotography. The chromatic aberration is reduced by the 2-element ED lens. To guarantee sharpness in the image field, you will need suitable correctors, which are linked in the accessories section.

WiflatM48 1.0x Image Field Corrector:
The corrector is simply inserted into the 2" receptacle of the focuser. Tilting is not possible. The focal length is not changed. The working distance from the M48 connection thread on the camera side is 55 mm.

TSRED110 - 0.8x focal length reducer and image field corrector:
The reducer connects via the 2" barrel and shortens the focal length to 616 mm. The speed is increased from f/7 to f/5.6. The large focuser also provides good illumination here and allows connection of cameras with sensors up to APS-C format and even beyond. The working distance from the T2 (M42x0.75) thread to the sensor is 55 mm - ideal for DSLR cameras, for example.
