Details

With teleextenders 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 smaller, compact Deep-Sky objects with the same eyepieces. So when using the Explore Scientific Focal Extender 3x, you can use the advantages of eyepieces with longer focal length - such as longer eye relief and more generous width of ocular lenses. The resulting benefits of using longer focal length eyepieces with this Focal Extender, generally lead to a more relaxed observing at high magnifications.

The Explore Scientific teleextenders incorporate a telecentric optical design, that deliveres a excellent image sharpness over the whole field of view and are premium choices for both visual observations and astrophotography. The combination of excellent fully multicoating with superior optical design makes these Focal Extenders superior to classic doublet Barlow lenses.

Features:

Suitable for visual observations and astrophotography
Triples the effective total focal length of the telescope
Four lens telecentric design
Fully multicoated
Filter thread for color or nebula filters
