LUFTHANSA ROOF-PRISM 8X42 BINOCULARS Water Proof – HIGHLY RECOMMENDED
Waterproof 8*42 binocular sponsored by Bresser has one of the best price/performance ratios. The magnification of 8x and an optical aperture of 42mm offers a total field of view of 105m. A diopter adjustment allows diopter corrections up to +- 2. A high-quality fully coating on all glass elements reduces distracting reflections, improves the light transmission, and provides a high contrast also in bad light conditions.
Another highlight of the Lufthansa Binocular is a handy and stain resistant rubber face, which is also responsible for the water resistance.
Furthermore, there is a transport bag and a comfort strap included.

The Bresser Messier AR-80/640 Nano Refractor Telescope is a complete beginner’s telescope. It’s a 3-inch achromatic refractor that’s bundled with everything a newcomer needs to get started: a manual altaz mount, a red dot finder, a star diagonal and a 26mm Plössl eyepiece.
Its 3-inch aperture is more than adequate to allow observations of a wide range of celestial objects, its altaz mount is intuitive to use and the whole thing is a doddle to set up.
Achromatic doublet lenses, like the ones in this scope, are made from two types of glass that work together to minimise chromatic aberrations – an unwanted effect that produces coloured halos around bright objects.
More expensive optics have a number of special coatings applied to reduce reflections and increase light throughput, but this lens assembly has only one coating of magnesium fluoride (MgF2) – the minimum required.
The inside of the seamless aluminium optical tube is nicely blackened, though and has a single baffle to help reduce unwanted internal reflections.
