This product allows the attachment of a Canon T-ring adapter to a 2.4" Televue focuser lens. I am using a Tele Vue Universal Paracorr lens as a coma corrector for a fast Newtonian astrograph. It requires the removal of the center ring of the standard Canon T-ring adapter using a hex key. This setup permits a wider aperture when using a DLSR for prime focus astrophotography.
This product has been misdesigned by Televue and is incapable of connecting a Canon Camera to anything. Televue now sells a CTW 2070 which performs the function the CTW 1070 was allegedly designed to perform. Under no circumstances should one purchase the CTW 1070. It is totally useless
