New old stock. (Hand Made by Paul Rini) 1.25" diameter 0.5X Reducer. This is just like a barlow, but instead of increasing power it reduces power. Why would you need this? It will give you a wider field view for visual views or CCD IMAGING!! Designed especially for use with new CCD eyepiece units. Reduce the effective focal length of your telescope by 1/2. Coated achromatic reduction system needs 25mm in-focus. Machined aluminum. 2.8" height. Set screw holds CCD or 35mm cameras. Accepts 1.25" accessories and fit 1.25" focusers. Threaded for 1.25" filters. Dust caps. You could pay up to $100 for a similar item, but this offering is much less than that!!
