BRESSER Achromatic 3x (1.25") Barlow Lens (Refurbished)

With the introduction of the 68° Series we are pleased to make two important improvements in eyepiece manufacture, the first being 15 layer Enhanced Multi-layer Deposition (EMD™) coatings on all glass-to-air surfaces to gain maximum contrast, and waterproofing the eyepiece with the use of Argon gas purging instead of standard Nitrogen gas. Although Nitrogen is a fine choice that will last for many years, Argon is a larger molecule that maintains its protective properties over a wider range of temperatures, and is even more resistant to diffusion thereby further extending the protective waterproof environment of the eyepiece body. Through computer-optimized design, a careful selection of optical glasses, and enhanced multi-layer deposition coatings, the Explore Scientific 68° Series™ eyepieces produce long eye-relief and ensure high image-correction, a flat field, and high contrast across the entire image field. An excellent choice for those who make extended visual studies of detail with subtle variations of brightness, and for those who must wear glasses while observing. All 68° Series eyepieces are fully EMD (Enhanced Multi-Layer Deposition) coated and edge-blackened to produce superior contrast.

Small but feature-packed: The NATIONAL GEOGRAPHIC ILUMINOS 1000 LED Zoom torch 1000 lm weighs just 107 g and is ideal for outdoor adventures. Despite its compact design, the small torch is packed with features. Whether you’re on a cave tour or camping in a tent, the powerful 1000 lm light will shine white light into any dark corner. It is also highly versatile, featuring a zoom focus that allows you to quickly adjust the light beam. You can direct a wide beam of light at your immediate vicinity, or focus on more distant objects. With this torch, you will quite literally see your surroundings in a different light. Zoom torch for outdoor activities The torch features a number of different modes for outdoor adventures. These include a flash mode for drawing attention to your location, and a dim function that dims the light to 50% - perfect for nighttime reading in your sleeping bag. An additional highlight is the strong magnetic clamp: if you’re cooking in the dark or in your tent making preparations for the next day, two hands can be useful. The magnetic clamp allows you to clamp the zoom torch to a suitable metal object, freeing up your hands for other tasks. The small torch is also splashproof, so you don’t need to worry about putting it away if you get caught in a shower while trekking or camping.
