15-30X80 Zoom Astronomy Binoculars with Built-in Tripod Mount Giant Binoculars with Phone Adapter and Case for Bird Watching Hunting and Stargazing

The zoom binoculars feature a wide variable range of 15-30X magnification that allows easy targeting and then zooming in for a closer, detailed look. These long range binoculars are designed for long distance terrestrial and astronomical viewing. Astro binoculars with 80mm large objectives offer a wider field of view than 50mm. The BAK-4 fully multi-coated prism with 21mm green film FMC eyepieces ensures better light transmission and brings you crystal clear views in low-light and long-range conditions, with higher-contrast images while reducing color errors and distortions. With the easy-to-reach control knob on your left hand, it is more convenient and quick to change the magnification from 15X-30X.

The right diopter ring can be adjusted to meet different vision requirements between two eyes. Long eye relief is also ideal for eyeglass wearers. The metal built-in tripod mount makes the binocular perfect for viewing objects far away, even celestial viewing. The phone adapter with rubber sucker, which allows 180° angle and length adjustment, is easy to set up and take images. The zoom binoculars come with a carrying case and strap. The protective rubber covering for an ultra-firm grip ensures product durability for long-time use. You needn't worry about getting caught in unexpected tough weather.

Easily focus on the target using the precise central adjustment wheel.
