These allow high magnifications in all sorts of light, thanks to their large-diameter exit pupils. These scopes use 1.25 diameter eyepieces, which allow less compacting of the light shaft produced by the objective lens and thus a larger image with superior depth perception.
In addition to Pentax eyepieces, you can also use astronomy eyepieces from telescope manufacturers such as Meade, Celestron and Tele Vues. The PF-100ED has a focal length of 630mm, so if you're using conventional 1.25 eyepieces you divide 630mm by the focal length of your eyepiece to determine the effective magnification. The Pentax ED scopes function brilliantly in many conditions of light and climate, and are remarkably light thanks to their metallic alloy housing. 20.0 x 5.3 x 184.108.40.206 x 9.7 x 9.4.
