The Docter UWA is a premium wide angle astronomical eyepiece, by many considered the top choice at this focal length. Both optical performance and ergonomics are of the highest level. 

The DOCTER Ultra Wide-angle Anastigmatic eyepiece features an outstanding optical performance. It provides the observer with a matchless panorama view with minimal distortion.

The DOCTER UWAs unique optical design utilizes technology developed within progressive lens making. The special optical design uses glasses with abnormal dispersion path – normally applied for extremely high-grade objects only – that significantly reduces chromatic aberration.

The Ultra Wide-angle Anastigmatic eyepiece reflects point-shaped objects throughout the entire field of view stigmatically (stigma = point), i.e. in a point-shaped manner.

High-grade lead and arsenic-free glasses with high internal transmission from top-ranking brand manufacturers are used exclusively in the 8 lens 5 group configuration of the DOCTER UWA.  All optically effective surfaces of these glasses are finished with broadband anti-reflect coatings. Hence, in spite of the high number of lenses, highest transmission values are achieved.

Thanks to its long eye relief, as well as its narrow barrel and eyecup design, the DOCTER UWA is optimally suited for binocular use in a binocular telescope or binoviewer. Pupil aberrations are minimal to enable an ergonomic and easy view of the whole field of view.

The DOCTER UWA comes with an easy to handle, spectacle and skin friendly foldable eyecup. The eyecup could be removed to provide the option of connecting filters or ancillary optics (e.g. digital cameras). The proven DOCTER grooves in the aluminium casing facilitate easy handling, with gloves or bare fingers.

A special type of sealing and the use of toroidal rings keeps the DOCTER UWA eyepiece watertight.  The unit is compliant with the common telescope standards and the regulations governing the use of hazardous substances (RoHS).

The DOCTER UWA comes with a 2 year limited warranty.
