Bresser 80/640 EQ Doublet
The achromatic objective lens in the BRESSER collects 30% more light than a 70mm telescope and already makes the first details on Mars visible. The rugged aluminum tripod gives secure footing on almost any surface and is easily and quickly set up thanks to its clever design.
This refractor telescope is equipped with an equatorial mount (also known as a parallactic mount). This allows for the compensation of earth rotation and the exact following of the celestial object observed.

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.
