2006-2012 taken with a Philips ToUcam on driven Celestron Mounts using an 8" Newtonian at F15. The 2013 version was taken with an Imaging Source Monochrome CCD camera on a 8" Newtonian at F20. All images made on nights close (+/- 1 day) of Opposition each year so the Seeliger Opposition Effect brightens the rings as much as possible.
