9mm Ploessl eyepiece (1 ¼ ')

These Plössl eyepieces represent a signifi cant evolution of the classic Plössl design. The five- or six-element design provides a better image quality and contrast throughout the big 60 degrees field of view combined with a comfortable eye relief. These eyepieces deliver pinpoint stars throughout the field of view and high contrast because of modern glass materials. High quality coatings and blackened lens edges and internal surfaces maximize contrast even further. The eyepieces are parfocal.
