The UWAN eyepieces from Teleskop Service offer an extreme field of view of 82°. They are the latest generation of this eyepiece class. We put a lot of emphasis on even better insight, more contrast and binoculars. The UWAN 4mm from TS Optics sets standards in the field of large field oculars.

The UWAN 4mm is an eyepiece for maximum magnification. It is a planetary eyepiece and at the same time an exciting deep-sky eyepiece. Lunar craters and the finest details on planets can be perfectly observed. The viewing behavior is incomparably better than with a Plössl or Ortho eyepiece. But even bright planetary nebulae or binary stars can be well observed with this eyepiece. Image brightness and contrast are guaranteed by multi-coating and clean interior blackout.
