Omegon Zoomstar 15-45×80 - Powerful zoom for clear observations
The Omegon Zoomstar 15-45×80 is a large, bright binocular that lets you enjoy clear images both during the day and at night. With a lens aperture of 80 mm, it captures a lot of light so that stars, animals or landscapes are clearly visible.
Flexible in use
You can easily zoom in from 15× to 45×. This allows you to see the entire landscape as well as the smallest details. The central focus wheel lets you focus quickly, so your images always stay clear, even with moving subjects.

Stable and comfortable
The metal tripod adapter is sliding, allowing you to find the perfect balance for stable observations. The rubber eyecups fold over for comfortable viewing, even with glasses.
Multicoating for clear images
All lenses have full multicoating. This reduces reflections and increases contrast. This keeps your images clear and sharp, even at higher magnifications.

Practical advice from the experts
Note: Zoom binoculars may cause a slight tunnel feel. For a more natural viewing experience, advanced observers often choose a fixed magnification, such as the Omegon Nightstar 20×80 or 25×100.
What we recommend
✓ Clear visibility during the day and at dusk
✓ Tracking animals and birds well with 15-45× magnification
✓ Astronomical objects clearly visible
✗ Not waterproof, so caution in rain
✗ Tunnel effect at maximum zoom
