The Vixen Optics #3907 Barlow Lens T is a 2x Barlow lens that inserts into 1.25" focusers or diagonals (when used with a diagonal, effective magnification is 3.3x instead of 2.0x).

This Barlow can be used conventionally for observing with a 1.25" eyepiece, but it can also be used as a SLR photo adapter.  On the observing end of the unit there's a T-threading; simply attach a Vixen T-mount (listed here as accessories) to use this Barlow together with your SLR camera.

    2x Barlow Lens (1.25") with Built-In T-Mount Adapter is rated 3.5 out of 5 by 2.
    Rated 5 out of 5 by from Back focus Provides a good image, want to measure the MTF at some point, but the main thing is that it provides a little extra back focus for a telescope as my camera will focus with it but not without it.

    Rated 2 out of 5 by from Not as good as expected My unit had a burr on the top edge and the eyepiece would not fit. Then the small thumb screw was stripped.
