Updated with new photos. Seldom used Astro-Physics 27TVPH Telecompressor with pristine glass for sale. Has 2.7 inch AP threads on each end - see full description at Astro-Physics website under category "Accessories - Telecompressor Reducers." I no longer have the original box. I used this to get a larger field of view on my 16 inch F8.4 RC scope equipped with an APS-C size camera sensor. I have now moved to a full frame camera for a wider field and eliminated the need to change the optical train configuration. There are two small set marks on the lower end of the inner barrel (see photos). These are outside of the optical path and have no optical effect. In addition, the marks are not visible when the 27TVPH is installed in the ptical path. Priced at $175 plus shipping (38% off new price). Accept Zelle, Venmo and PayPal (add 3% if using Goods and Services).
