Omegon Argus 25x100 Binoculars
Nature does not stop when the sun goes down. Nocturnal wildlife, star clusters, nebulae - all of this is waiting for you, as long as you have the right instrument. The Omegon Argus 25x100 binoculars gather a large amount of light thanks to their 100 mm lenses and 25x magnification, making them highly effective at dusk and in complete darkness.
Lightweight yet tough
Beneath the rubber armour sits a magnesium body. This is why these binoculars weigh noticeably less than comparable instruments with a metal body - yet they remain impact-resistant and ready for demanding outdoor conditions. During long sky-watching sessions, every gram saved makes a real difference: your arms stay fresh longer, and you can focus on what you see rather than on holding the instrument steady.
Clear, neutral image from edge to edge
BAK-4 prisms combined with fully multi-coated (FMC) anti-reflection coatings on all lens surfaces ensure that light reaches exactly where it should - your eyes. The result is a neutrally balanced image without the yellowish tint that affects cheaper instruments. Contrast stays clean from the centre all the way to the edge of the field of view. The eight-element optical design maintains sharpness throughout, with minimal softening towards the edges.
Adjustable focus for each eye
Each eyepiece focuses independently. The single-focusing system with dioptre correction on both sides lets you set the image precisely for each eye. The fold-down eyecups are designed so that observers who wear glasses can see the full field of view without any clipping at the edges. The binoculars feature a tripod adapter thread, so you can mount them securely for long observation sessions.
Nitrogen-filled and waterproof
The Omegon Argus 25x100 is nitrogen-filled and fully waterproof. Internal condensation and rain at an outdoor observation post will not affect the optics.
