Bresser Special-Astro Porro Binoculars 20x80

If you are specifically looking for astronomy binoculars or a pair ideal for long distance viewing, then the 20x80 Bresser Special-Astro Porro Binoculars are an ideal choice. These are porro prism binoculars with fully multi coated BAK-4 prisms, which are considered the best type of Porro prism as they are made of superior optical glass to produce clearer images. Bresser Special-Astro Porro Binoculars 20x80 feature a diopter adjustment and foldable rubber eye cups. They can directly be mounted onto tripods with standard 1/4" attachments, this is a useful feature as these astronomy binoculars although made from aluminium weigh over 2 kg, and we'd recommend using a tripod to support these binoculars when in use. The large 80 mm objective lens on these binoculars affords excellent light gathering qualities, and their optical design and fully multi-coated lenses minimise stray light, ensuring a crisp clear image.  In addition to a five-year warranty, these Bresser Special-Astro Porro Binoculars also come with a quality nylon carrying case with carrying strap.    Features     Binoculars for astronomical and long distance observations     Extremely high light gathering capacity     Can directly be mounted onto tripods with standard 1/4 inch attachments What's included in the box     Binoculars     Carry case Specifications Type:     Standard Binoculars Optical Specifications Optical design:     Porro Magnification:     20 LE Eyepieces:     Yes Mirror/Lens diam.:     80 mm Material prism:     BaK-4 Type of coating:     Fully multi-coated Colour of coating:     violet Eyepieces for eyeglass wearers:     Yes Diopter setting:     Yes Field of view at 1000m:     56 m Light intensity:     16 Twilight factor:     40 Near focus from:    40 m General Technical Data Bag/Pouch:     nylon carrying case with carrying strap Colour:     black Body material:     Aluminium Tripod adapter thread:     Yes Focusing system:     Central focus wheel Eye cups:     Rubber eye cups, foldable Interpupillary distance min.:     57 mm Interpupillary distance max.:     72 mm Body armouring;     Rubber/Plastic Dust protection caps for objective and eyepiece, individually removable Extended warranty:     5 years Net weight (without access.)     2100 g Shipping Weight:     2.953 kg   Dimensions: 330x235x108mm
