With teleextenders it is possible to extend the effective focal length of a telescope system, resulting in higher magnification for observing the moon, planets or small deep sky objects with the same eyepieces. Therefore, you can take advantage of the benefits of eyepieces with longer focal lengths, such as longer eye distance and more relaxed observing comfort, also at high magnifications.
These tele-extenders incorporate a telecentric optical design that provides excellent image sharpness over the entire field of view and are premium choices for visual observations and astrophotography .The combination of an excellent full multi-coating with a superior optical design makes the focal extenders superior to classic Barlow lenses.
