Inexpensive eyepieces, which are often included in the scope of delivery of complete telescope sets.
Plössl – popular and inexpensive all-rounder
Plössl eyepieces are the standard astronomical eyepiece and are affordable for everyone. Plössl models are often found in complete accessory sets. Plössl eyepieces always consist of four lenses grouped in two pairs. These pairs of lenses are cemented together and each pair form an independent achromat, i.e. they have virtually no colour defects. With a short focal length, however, the eye relief is a problem. This means: here the lenses are so small that you have to get very close to the eyepiece. In this range of focal lengths other eyepieces may make more sense. The apparent field of view is about 50°.
