An eyepiece for every occasion, with very good field correction and large field of view.
The BRESSER Zoom Deluxe Eyepiece covers the wide focal length range from 8 to 24 mm. These are also the focal lengths most commonly used with most telescopes. Especially for instant observations, without having to fill an entire suitcase with eyepieces, this zoom eyepiece is a good choice. The Deluxe version offers, thanks to its especially advanced optical design with 9 elements in 6 groups, even better field correction and sharpness combined with a large apparent field of view from 40 to 62 degrees.
Always the ideal magnification at hand
A quick twist and you have the ideal magnification already set. Adjustment is continuous from 8 to 24 mm focal length. This eliminates the need to always change eyepieces.
A comfortable view
The BRESSER Zoom Deluxe eyepiece offers a large comfortable eye relief (LER) of 20 mm to the eyepiece lens. This means comfortable viewing even during prolonged observation, an important criterion especially for spectacle wearers. The rubber eyepiece can also be individually adjusted by a twisting movement.
Advanced optical design
To achieve the best possible image over the entire focal length range, a particularly advanced optical design with 9 lenses in 6 groups is used. Full multi-coating of all lens surfaces also ensures maximum light transmission. To effectively suppress unwanted reflections, all lenses are carefully blackened at the edges. Thus, the image produced offers the highest possible contrast and image brightness.
Compact and solid design
The BRESSER Zoom Eyepiece Deluxe is made entirely of black anodized aluminum. It has an extremely solid, high-quality material appearance and is very durable, even with intensive use. The precise zoom mechanism can be securely adjusted via the rubberized adjustment ring. A white laser engraving with the focal length and pointer arrow shows the current focal length setting even in low light.
