Product description Anyone who seriously wants to observe at a high level needs a powerful optics. Our APM MS 100mm binoculars already have 3x as much light collecting area than 50mm binoculars. This results in a significantly increased resolution, limiting magnitude (astronomy) and magnification in the terrestrial area. New fields open up for the nature observer, as distant objects remain recognizable even in difficult light situations. The amateur astronomer will appreciate the increased object brightness, which makes detailed observation much easier. The price-performance ratio is excellent! The large 4 "ED optics are modern, multi-coated, as also the BAK-4 prism system is. This enables sharp, high-contrast and bright object imaging, even in difficult light conditions. Our model 34x100 offers an AP of 4mm, an optimal value for long-term detailed observations. But a tripod is recommended for observation (adapter included). The APM Magnesium binoculars uses high quality ED glass (FK61) as well as BAK-4 prisms for maximum contrast and highest sharpness over the entire field of view. Special coatings on all optical surfaces eliminate disturbing reflections and ensure natural colors. With a interpupillar distance of 16mm, the eyepiece construction is good suitable for people who wear glasses. The rubber eyecups can be folded down. The entire system got the IPX-7 certification for protection against the ingress of water. Our binoculars is completely protected against rain and immersion in water, so it is completely weatherproof. The magnesium body is very lightweight and yet very robust. A rubber armouring is attached to the housing, which further protects the glass and gives you a secure grip and hold. Delivery: Binoculars ED 34x100 Tripod adapter Carrying case Lens hoods
APM Ceramic Safety 2" Herschelprism with APM Fast-Lock Eyepiece Adapter.For solar white light imaging and white light visual observing. The APM White Light Wedge comes with a built in ND3 filter which allows perfectly safe imaging or visual observing of the Sun. The APM Herschel prism is equipped with the ceramic light trap, an multicoated integrated multicoated ND3 filter and (removable) multicoated polarizing filter. The sun can be safely observed with the APM Herschel Prism.The image brightness can be adjusted by twisting of the 2 "polarizing filter by rotating the 2" eyepieceholder from outside . Thus, the Herschel Prism can be used both visually and also photographically same good!
Glas FK61 (similar to Ohara FPL51), has blackenededges, a measured transmission von over 99% from 400 nm to 700 nm, optimized for F/4 Newtonian-Telescopes. The barlow has a negative focal length of - 62.9 mm and a working backfocuse of 105 mm from center last lens to focuse ( eyepiece field stop). You will need now a 1.25" eyepiece holer 104 mm long
