APM
APM 82mm SD ED APO BINOCULARS 90° is backordered and will ship as soon as it is back in stock.
The APM 82mm SD ED 90° Binoculars are high quality apochromatic binoculars with doublet lenses and BAK-4 prisms for high contrast views of astronomical and terrestrial objects. All optical surfaces are fully broadband multi-coated for high transmission and contrast.
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 1.25" eyepieces such as those by Baader. The interpupillary distance can be adjusted and each eyepiece can be individually focused. Thanks to the standard 1.25" 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.
Note: Eyepieces are not included. It is highly recommended to mount these on a tripod such as the incredibly sturdy Geoptik Binoplus Pantograph mount.
