This is an Alstar (Generic) 0.5x 1.25" focal reducer, threaded to accept filters.  It is in excellent condition, with clean optics and body.


The 0.5x focal length reducer effectively halves the focal length of the telescope to achieve lower magnification, wider field of view and shorter exposure time for astrophotography. This focal reducer is compatible with most 1.25" accessories.
