Attached are six Shadow Transits of Titan (I was unaware of the April 30th Transit).   Four more to go- Aug 19th, Sept 4, Sept 20, and Oct 6th.   All are basically a fortnight apart!    All images taken through horrific weather conditions through clouds, haze and humidity.   Fortunately, the seeing was above average.    I chose the best image from each observing session.  
Note how the shadow begins just above the rings and gets higher and higher on the disk with each successive observation.   In addition, the angular diameter of Saturn is increasing.  (all images were taken using the same optical hardware).   How cool is that!
