Levenhuk Ra 40 mm 2" ED is a low-powered parfocal eyepiece that performs equally well during terrestrial and celestial observations. With its optical elements made of ED glass, this eyepiece has a high light transmission; and thanks to the fully multi-coated optics, the observed views are always sharp.
The edges of the lenses are blackened to eliminate glare from observed bright objects. With its 2'' barrel diameter, this eyepiece can still be used with a 1.25'' focuser with a special adapter. Therefore, this eyepiece can be used with a telescope of any brand and make. The eyepiece shell is made of lightweight aluminum.
