All bird images were taken by Mr. Derry Mount through a Tele Vue-85 telescope, the indicated Tele Vue eyepiece, and a Nikon Coolpix 990 (2,048 x 1,536 pixels maximum resolution) digital camera. A Tele Vue Digital Camera adapter was used to solidly mate the camera's non-removable lens to the Tele Vue eyepiece. The long eye relief designed into many of Tele Vue's eyepieces allows for afocal imaging with minimum vignetting. This system of "afocal" imaging is a convenient way to take telephoto images with cameras that have non-interchangeable lenses.
