Takahashi Extender
I doubt I will ever use this ....
Takahashi Variable - Extender ... Superb Condition .
This is a screw-in Barlow-type device
Recommended for use with Takahashi refractors
Recommended are the FS Series and SKY-90
Unit is a 1.6 X "telenegative amplifier" lens assembly (read "Barlow"), three extension tubes, and a 1.25" eyepiece adapter
By varying the number of extension tubes you can change the Barlowed power by 1.6 X to 3.0 X
Unit suits visual & high-magnification photography
