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 multi-layer anti-reflection MC coatings.

Wide eyecups and large diameter eyepiece lenses make every observation a pleasure.

The Discovery 16x50 binoculars are a high-magnification model, significantly exceeding the zoom achieved by the basic Discovery 10x50 model, although with a rather narrow field of view.

Especially recommended for daytime observations of distant terrestrial targets.

It can be successfully used for observing aircraft at cruising altitudes.

For astronomical observations, it is better to use them for bright objects, such as the Moon.
