Focal Extenders

Available in 2x, 3x and 5x in a 1.25” barrel and 2x in a 2” barrel, Explore Scientific focal extenders add versatility to your eyepiece line-up by allowing each eyepiece to perform at two powers. For example, if your particular eyepiece/telescope combination results in a 50x power, adding a 2x focal extender will change that to a 100x power.
