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.
