I took this pic of the rings with my iPhone (love 21st century technology!). Obviously, I couldn't hold the phone exactly on axis, but I got a lot closer than I could with my haid. The ghost rings are due to reflections viewed off axis.
How does this look? (other than the obvious grunge from the spacers and the dirt that's enhanced by the technique and my stretch of the image!)
