This tele-extender fits the Vixen ED and fluorite refractors only. It does not use an eyepiece to increase the magnification, as with other tele-extenders, but rather has a built-in fixed magnification. The 720mm focal length f/9 80mm ED refractor ED80S increases to a 1296mm f/16.2 system. The 920mm focal length f/9 102mm ED refractor GP ED102S increases to a 1656mm f/16.2 system. The 640mm focal length f/8 80mm GP FL80S fluorite refractor increases to a 1152mm f/14.4 system. The 920mm focal length f/9 80mm GP FL102S and GP-DX FL102S fluorite refractors increase to 1656mm f/16.2 systems. The tele-extender threads onto the focuser drawtube of the above scopes, in place of the eyepiece holder. An optional T-ring to fit your particular camera is required.
