Eyepiece for 99 mm scopes

The TE-11WZ II is a wide-angle zoom eyepiece built for 99 mm Prominar spotting scopes and also fits 88 mm and 77 mm models. It provides a 30-70x magnification range on the 99 mm series and 25-60x on the smaller scopes. Birdwatchers, stargazers and long-range observers gain a single eyepiece that covers multiple instruments.

Dual magnification markings

Because the 99 mm scope has a longer focal length, the eyepiece carries two magnification scales so the reading stays accurate on every compatible model. The wide-angle design delivers a field of view from 105 to 60 feet at 1,000 yards across the zoom range, meeting or exceeding other wide-angle zooms.

30-70x on 99 mm series

The magnification range shifts with the objective size: 30-70x on 99 mm scopes and 25-60x on 88 mm or 77 mm scopes. Buyers who need a fixed focal length or a different zoom span should look elsewhere.

Questions about this item

Does the eyepiece need periodic cleaning or seal replacement to maintain optical performance?

The optical surfaces benefit from occasional cleaning with a lens cloth and blower; the unit has no user-serviceable seals or internal parts that require scheduled replacement.

At 70x magnification on the 99 mm scope, what is the field of view at 1,000 yards?

At the 70x setting the field of view is 60 feet at 1,000 yards.

Does the eyepiece barrel become noticeably warm or draw power during all-day observation?

The eyepiece is a passive optical component with no electronics, so it generates no heat and consumes no power regardless of how long it is used.
