The APM 150mm ED 45° Binoculars are high quality apochromatic binoculars with FK61 doublet lenses for exceptional views of faint astronomical and terrestrial objects. All optical surfaces are fully broadband multi-coated for high transmission and contrast.
The use of FK61 glass objectives result in excellent colour correction with minimal residual chromatic aberration and truly apochromatic performance. With massive 150mm objectives, it is possible to observe faint nebulae and make use of higher magnifications for planetary and Lunar viewing. Due to the way the brain sums two images together, you will be able to make out fainter details than when using a single telescope of similar size, particularly when adding nebula filters.
The extendable dew shields protect the lenses during long observations and can be used as a light shade during daytime viewing. The binoculars include a tripod mounting connection and a heavy duty carrying handle. The nitrogen-filled housing is weatherproof and made of magnesium alloy for maximum rigidity and lightness.
APM binoculars are designed to provide comfortable focus position with common high-end 2" eyepieces. The interpupillary distance can be adjusted and each eyepiece can be individually focused. Thanks to the standard 2" holders, wide-angle eyepieces can be used.
Both 90° and 45° versions are available. Typically 45° is better suited to low altitude astronomical objects and earth observation, with the 90° version providing a more comfortable position for high altitude astronomical objects.
150mm APM binoculars are tested and certified for 100x magnification.
Note: A pair of 30mm Ultra Flatfield eyepieces and a hardcase are included.
