The Opposition Effect of Saturn

I’ve just assembled this new montage of images of Saturn from the 2007–8 apparition for publication in a book authored by my friend Dominic Ford. It shows the Opposition Effect, whereby Saturn’s rings become abnormally bright at low phase angle.

From the top, they are 2008 February 25 00:31 (taken within eight hours of zero phase angle between Earth, Sun and Saturn), 2008 February 26 23:27, and 2008 March 04 23:56. All taken at Stag Lane observatory through the C-14 with Lumenera SkyNYX 2-0 camera.
