Explore Scientific premium 1.25" 2x / 3x / 5x Barlow / Tele-Extender an excellent choice for visual observations and astrophotography.
With tele-extenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for the observation of the moon, the planets or small Deep-Sky objects with the same eyepieces. So you can use the advantages of eyepieces with longer focal length - such as the bigger eye distance and the more relaxed observing comfort - at high magnifications also.
These tele-extenders incorporate a tele-centric optical design that delivers a excellent image sharpness over the whole field of view and are premium choices for visual observations and astrophotography. The combination of excellent fully multi-coating with superior optical design makes the Focal Extenders superior to classic Barlow lenses.
