Saturn with Titan

This image of Saturn with its moon, Titan, at about 11:00 at the top of the image was taken using a 17 mm eyepiece in a process called "eyepiece projection" for 1.5 seconds.  This means that the camera body didn't have a camera lens, but instead was married to the 17 mm eyepiece, which, in turn, was set (as usual) in the eyepiece cradle on the telescope.  This makes the telescope a huge telephoto camera lens with extra (higher) magnification than with prime focus.  This technique is ideal for planetary photography.
