According to the manufacturer's website: The 196-1 allows complete flexibility, combining the features of the 191 and 192 eyepiece units. A rotating filter disc provides five options: "see-through" capability, reticle projection, green-filtered light, beam splitter with no coating, beam splitter with partial coating. A built-in diffuser may be engaged for even light distribution over the entire field of view when autocollimating, collimating, or colineating. By removing the light source, the 196-1 operates as a fixed right angle eyepiece. The unit comes complete with model 501 light source. The 196-1 is installed by replacing the removable adapter tube on the ocular end of many of our telescopes (right). Unit does not come with a light source.
