Description Technical Specs
This versatile barlow lens, from Vixen, will double the magnification when placed immediately before an eyepiece.

It also has t-threads at the top. It can be used to connect a camera, with the use of a T-ring, to any telescope. The front lens can also be unthreaded to make this a pure 1.25" camera adapter.

A third use for this barlow is to remove the front lens and thread it directly into an eyepiece, creating 1.5x magnification or in front of a diagonal to create ~3x.

A barlow effectively decreases the eyepiece's focal length by the amount of the Barlow's divergence. Since the magnification provided by a telescope and eyepiece is equal to the telescope's focal length divided by the eyepiece's focal length, this has the effect of increasing the magnification of the image. The amount of magnification is one more than the distance between the Barlow lens and the eyepiece lens, when the distance is measured in units of the focal length of the Barlow lens.
