Very Short Construction
Use this Barlow where in particular where you need a shorter length. Sometimes the total accessory length with eyepiece, adapter or camera can be rather long. The optical path of Astromania 1.25" 3-Ele-ments 2x Barlow Lens is only 43mm.
Easy To Use
Simply insert the 1.25" 3-Ele-ments 2x Barlow Lens into your telescope's focuser or diagonal, and then insert any 1.25" eyepiece into the barlow lens, gently securing it in place with the knurled set screw grips. Then, adjust the telescope's focus wheels to enjoy double the magnification of the eyepiece used.
