The Levenhuk Ra Plössl 4 mm, 1.25” eyepiece is a universal accessory for telescopes (particularly suitable for planetary telescopes). This eyepiece can be used with telescopes of any make or optical design. The diameter of the eyepiece barrel is 1.25”.
Thanks to its multi-element, fully multi-coated glass optics, it produces sharp, detailed images across the entire field of view, which is 55°. This is an excellent specification for eyepieces in this category. Its lenses minimise most optical aberrations; the centre of the field of view offers the highest resolution.
The eyepiece body is made of aluminium.
