BRESSER 20mm Plössl Eyepiece 1,25″ (31,7mm)
Since years a well known and approved Plössl eyepiece. Ideal to improve the performance of your telescopes for a low budget price.
All the BRESSER Plössl eyepieces provide sharp and high-contrast images because of the 4-lens design. All lenses have fully-multicoated surfaces which prevents reflections efficiently. Every eyepiece is equipped with a foldable rubber eyecup to avoid straylight from the sides and the inner eyepiece shaft is carefully blackened as well. Housing and eyepiece shaft are completely made from metal — no plastic is used. Filter thread for use with colour- and nebular filters is also available.
All these Plössl eyepieces offer a much better image quality than all the very simple made Kellner and Huygens eyepieces.
