{"product_id":"7326","title":"Delta Optical Binoculars Discovery 16x50 - High Magnification for Distant Viewing","description":"Delta Optical Discovery 16x50 Binoculars The Delta Optical Discovery series of binoculars includes models with a durable construction based on a solid aluminum and rubber-coated body. The lenses used in Discovery binoculars are coated with effective multilayer anti-reflective coatings. Wide eyecups and large eyepiece lens diameters make every observation a pleasure. The Discovery 16x50 binoculars are a high-magnification model, significantly exceeding the close-up achieved by the basic Discovery 10x50 model, although with a rather narrow field of view. Especially recommended for daytime observations of distant terrestrial targets. They can be successfully used for observing aircraft at cruising altitudes. For astronomical observations, they are better used for bright objects, such as the Moon. Technical specifications.
