.... (with engraved "Carl Zeiss" name on it!). This Barlow lens has been modified to allow for a multitude of modern functions. It has a T2 thread for easy adaptations of webcams, binocular viewers, ...
The eyepiece clamp has been replaced by the excellent Baader Click Lock clamp - a self-centering micro-focuser and eyepiece clamp that will not scratch your eyepieces.
Direct T2 Adaptation Available - Magnification Can Be Enhanced Up To 4x Without Degrading Images.
You can attach any SLR or DSLR camera to the Barlow lens using a T2 ring (also available here). The Barlow then functions both as a 1.25" adaptation for the camera and a Barlow lens at the same time. If you use the optional T2 extension tubes you can enhance magnification up to 4x without losing image quality.
These Barlow lenses are as precisely figured and polished as high quality refractor objective lenses!
