A tried and tested quality Plössl eyepiece in a classic four-lens design. Ideal for extending the eyepiece range of small and medium telescopes at a reasonable price. For high light transmission (image brightness) and to avoid reflections, all surfaces of the lens are provided with multiple treatment. All BRESSER Plössl eyepieces are equipped with a rubber eyecup that provides additional viewing comfort and prevents stray light from the side. The housing and eyepiece are made of quality metal and not plastic. A standard 1.25 inch filter thread for paint and fog filters is of course available. In order to further reduce annoying reflections, the inside of the eye protection terminals is carefully blackened. The short focal length (high magnification) is ideal for moon and planet reproduction. Long focal lengths (low magnification) allow you to supervise pretty observations of starry chickens and fogs with a pleasant distance between the eyes. All Plössl eyepieces offer significantly higher contrast and image clarity than standard cellar or Huygen eyepieces at a very good price. The BRESSER Plössl eyepieces thus significantly improve the overall conduct of your existing telescope and this with obvious financial effort.
