Product information "BRESSER Spezial Astro SF 15x70 Binoculars"
Thanks to fully multi coated Bak-4 glass material, the extra large objective 70mm lens diameter and highly corrected eyepieces with 5 lenses in 3 groups, these binoculars provide bright, crisp images from edge to edge of their field of view. The high 15x magnification is convenient not only for observing astronomical objects but is also practical for viewing distant terrestrial objects. Due to a very high reduction of stray light, the binoculars deliver the best possible picture and excellent clarity. With the individual eyepiece focus set you can get a sharp image for all astronomical distances, with no "focus creep" to spoil the view . Foldable rubber eyecups give eye glass wearers the possibility of making the best use of these binoculars wide field of view. Large diameter ocular eyepiece lenses provide extremely comfortable viewing, making longer observations possible without eye fatigue.
The binoculars are waterproof and ARGON gas filled to avoid internal fogging. The ergonomic rubber armouring provides a good grip and is also protected against shocks, making them rugged and ideal for transportation.
With the tripod thread in the lengthened centre axis, the SPEZIAL ASTRO can be mounted onto any photographic tripod. For tripod use the tripod adapter (part No. 4914925) is icluded. The use of a tripod is highly recommended, as hand holding at the high magnification of 15x makes it difficult to obtain a steady image.

- 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.
