Product information "BRESSER LER Zoom Eyepiece Deluxe 8-24mm 1.25'' (Refurbished)"
NOTE: This item is a used or returned product. This means: The item may show slight signs of use and the packaging may differ from the original packaging. Please note that refurbished items generally come with a 12-month warranty.
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.
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.

Warning notes
- General safety instructions DANGER Risk of eye injuries! Never look directly at the sun or near the sun through this device. There is a risk of blindness! Children should only use the device under supervision. Keep packaging materials (plastic bags, rubber bands, etc.) away from children! There is a risk of suffocation! FIRE HAZARD! Do not expose the device especially the lenses to direct sunlight! The light concentration could cause fires. RISK of material damage! Do not dismantle the device! In case of a defect, please contact your dealer. They will contact the service center and may send the device in for repair. Do not expose the device to temperatures above 60°C!
- Never look at the sun through an eyepiece/telescope without a certified protection filter. A moon filter can never be used for solar observation. The moon filter is only suitable for moon observation. The solar filter must be mounted in front of the telescope opening, not at the eyepiece. Otherwise, the concentrated light beam through the optics will immediately destroy the filter foil, leading to severe eye damage, including permanent blindness.
- Never leave the optics unattended. Children and inexperienced adults could point the telescope at the sun without proper precautions and lose their eyesight.
- Do not expose the device to high temperatures.

NOTE: This item is a used or returned product. This means: The item may show slight signs of use and the packaging may differ from the original packaging. Please note that refurbished items generally come with a 12-month warranty.Set of 5 extension tubes with T2 thread on both sides for exact distances and secure hold of cameras for astrophotography. Also comes with SC to T2 thread adapter.In astrophotography, most cameras are connected to a telescope via a T2 thread (M42x0.75), the most popular international standard. However, in many cases, T2 and T2-ring adapters for connecting telescope focusers to a camera are not sufficient, as specific distances must also be observed. This is especially important when using correctors, reducers or flatteners. This extension tube set, which consists of 5 mm, 7.5 mm, 10 mm, 15 mm and 30 mm tubes, will allow you to obtain almost any distance using the corresponding combination. Each tube has a T2 interior thread on one side and a T2 exterior thread on the other side.Most telescopes either include a T2 thread adapter, or the eyepiece can be used with a simple T2 thread adapter with a 2 plug-in diameter (item no. 0510365).However, Maksutov-Cassegrain, Schmidt-Cassegrain, ACF or RitcheyChrétien telescopes may use a so-called SC thread. To allow you to use this extension tube set with these telescopes, the set also includes an SD to T2 thread adapter.FEATURES5 T2 tubes with lengths from 5 mm to 30 mmCombination of tubes allows you to obtain distances of 5 mm to 67.5 mmFor exact camera distances in astrophotographyDELIVERY CONTENT5x T2 extension tubes (5/7.5/10/15/30 mm)1x SC to T2 thread adapter
