Description:
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 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 teleextenders incorporate a telecentric optical design that deliveres a excellent image sharpness over the whole field of view and are premium choices for visual observations and astrophotography. The combination of excellent fully multicoating with superior optical design makes the Focal Extenders superior to classic Barlow lenses.Four-lens telecentric teleextender 2xMultiplying the effective focal length by: 2xFully multicoated design with four lensesTelecentric optical design for excellent sharpnessAll lens edges blackened for maximum contrastEyepiece and teleextender barrel size: 2″Filter thread for color or nebula filters
