82mm diameter objective lenses are fully multi-coated to enhance viewing, ensuring clear visual range and sharp images. The eyepiece (standard:32X) is designed to provide a wide angle and high eye point for easy and less tiring viewing. Optional interchangeable 50X and 21X eyepieces are also available. The "Highlander" is not only for astronomy but fulfills the needs of observation and surveillance professionals.
High-end "Prominar" models, with Fluorite Crystal Lenses
Besides a normal "Achromat" lens, we have prepared a "Prominar Apochromat" model with fluorite crystal lenses, for those seeking higher optical performance. These fluorite lenses eliminate color blur (chromatic aberration) , improving resolution and contrast.
Waterproof Body with High Durability
The strong yet lightweight die-cast aluminum housing has high durability, with a rigid structure that can endure hard usage. The housing is waterproof and filled with dry nitrogen gas to prevent the lens from fogging. Eyepieces are set at a 45 degree angle, allowing for easy, long term observation.
