Focal multipliers 2x 50.8mm/2 "Explore Scientific

With focal (or teleconverters) multipliers, it is possible to increase the focal length of a telescope, which leads to higher magnification for the observation of the moon, planets or small objects from the deep sky. Thus, you can use the advantages of the long -distance focal length, such as the greatest ocular distance and the comfort of observation to high magnifications.

These high correction focal distance multipliers incorporate a design with four lenses which offers excellent image quality throughout the field of vision and are privileged choices for visual observations and photography. The combination of the excellent anti -reflective treatment and telecentric design makes focal multipliers far superior to the classic barlow.
