Bresser LER Zoom Eyepiece Deluxe 8-24mm 1.25 Inch

Product Description

One premium versatile eyepiece for all types of observing with any telescope, with excellent field correction and large comfortable field of view. The Bresser Zoom Eyepiece Deluxe covers the large focal length range from 8 to 24 mm. These are also the focal lengths most frequently used with most telescopes. Especially for instant observations, where you don't want to pack a whole suitcase full of eyepieces, the zoom eyepiece is a good choice. The Deluxe version offers with its particularly advanced optical design with 9 elements in 6 groups an even better field correction and sharpness, combined with a large apparent field of view of 40 up to 62 degrees.

Delivery Time
Delivery is usually around seven business days with this product which comes direct from the supplier.

Always the ideal magnification on hand
A quick turn and the ideal magnification for you is set. The adjustment is stepless from 8 to 24 mm focal length. This eliminates the need to always change eyepieces.

Comfortable viewing
The Bresser Zoom Eyepiece Deluxe offers a large comfortable eye relief (LER) of 20 mm to the eyepiece lens. This means a comfortable view even during longer observation, an important criterion especially for people wearing glasses. The rubber eyecup 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. The full multi-coating on all lens surfaces also guarantees maximum light transmission. To effectively suppress unwanted reflections, all lenses are carefully blackened at the edges. Thus, the image produced offers the maximum possible contrast and image brightness.

Compact and solid design
The Bresser Zoom Eyepiece Deluxe is made entirely of black anodised aluminium. It has an extremely solid and high-quality material appearance and is long-lived, even with extensive use. The precise zoom mechanism can be adjusted safely through the rubberised adjustment ring. A white laser engraving with focal length and pointer arrow shows the current focal length setting even in low light.
