Autobright Technology

Steiner’s exclusive sun-adaptive Autobright Technology automatically adjusts brightness to provide the best view in any lighting situation. Whether the sun is just below the horizon, shining directly overhead, or reflecting off water or snow at any angle, BluHorizons are designed to capture the right amount of light and reduce glare for optimal viewing.

Fast-Close Focus

Minimal, stepless focusing of the central drive for fast, maximum sharp details from close-up to infinity. Convenient and easy focusing.

Exceptional Durability

Thanks to the durable housing, water resistance, and functionality in a temperature range from -20 °C to +70 °C. The non-slip NBR Longlife rubber armor is resistant to oils, acids, and weathering.
