Product Properties

  • High image quality thanks to top quality BaK-4 prisms.
  • Exceptionally bright due to a 50 mm diameter lens and additional silvering of the prisms thereby increases their light transmitting capacity.
  • Eye-friendly observation since the silvering coincidentally reduces harmful UV radiation .
  • Absolutely watertight and thus suitable for any kind of weather.
  • Nitrogen filling prevents misting of the internal optics if the temperature fluctuates.
  • Spectacle eyepieces afford an optimal field of view even when wearing (sun) glasses.
  • Stable tripod thread ensures shake-free viewing pleasure at all times.
  • Accessories: Comfortable carrying strap, bag, protective dust caps.
