Kowa's answer to the competition's wide-angle zooms has a 25-60x/30-70xW magnification range and fits the 99- 88- 880- 770 series.
For the first time ever, Kowa has fitted an eyepiece with fluorite-containing XD glass in two of the total of 10 lenses in three elements. For that reason, the eyepiece is marked Prominar. Otherwise, it is the same proven concept with a modern eye cup for a full field of vision with or without glasses. However, they have succeeded in designing the eyepiece so that the eye distance is constant throughout the entire register. The shell is easily unscrewed for cleaning or mounting Kowa's digiscoping accessories. Kowa's internal designation is TE-11WZ on this eyepiece and it is moderately larger and heavier than the standard 20-60x.
