About this product
The Kowa Highlander features 82mm diameter, 450mm focal length (F/5.48) objectives that are fully multi-coated to enhance viewing, ensuring clear visual range and sharp images. The 32x eyepieces are designed to provide a wide field of view with ample eye relief for easy and less tiring viewing. Optional interchangeable 50x and 21x eyepieces are also available. The Highlander is designed not only for astronomy but also tofulfilthe needs of observation and surveillance professionals.
Besides the standard "achromatic" objectives, Kowa has designed a "Prominar Apochromat" model with fluorite crystal objectives for those seeking highest-possible optical performance. These fluorite lenses eliminate false color (chromatic aberration), which improves resolution and contrast.
The Highlanders strong yet lightweight die-cast aluminium housing is extremely durable, with a rigid structure that can endure hard usage. Weight is just 13.6 pounds with the standard 32x eyepieces. The housing is waterproof and filled with dry nitrogen gas to prevent internal fogging. Individual-focus eyepieces are set at a 45 degree angle, allowing for easy, long term observation of both terrestrial and astronomical targets. Also included are built-in retractable dew-shields that help protect against stray light and moisture.
Options include a selection of tripods/mounts, a high-quality aluminium carrying case, as well as wide-angle 21x and high-power 50x Kowa eyepiece pairs.
