My last post in January, Saturn Goes Commando, is about Saturn at its equinox. This means the rings are now edge on with the sun and at their thinnest from our vantage on earth. You cannot see the rings at all from my astrobinoculars. Check out this picture from Ciclops http://ciclops.org/view/5815/Shadow_South_of_Another?js=1
Ciclops.org is the official website for the Cassini mission. Check it out.
If you look on the sphere of the planet you can see the razor thin shadow line of the rings. That little bump on the ring shadow is the shadow of the moon Enceladus. Enceladus is not in the picture since it orbits beyond the rings but it still casts a shadow on Saturn.
Man I love this stuff.
