This ring is made from a small part of a huge Mandelbox based 3D fractal hybrid I blended many years ago.
You could say it is from a deep zoom of this fractal.
The reason I have stuck to this tiny part of the fractal is because of its diversified shapes, every branch you see is different in it's fractal shapes and that gives me great pleasure ;) It was one of the first 3D fractals I tried to 3D print when I came to SW, but I didn't succeed at that point.
Now, when I could do it I turned it into this Planetarium Ring. I love it!
Inner diameter of this version is 19.5mm, PM me or put a comment here for specific sizes!

Thank you NASA for images of the Moon, Mars and the Milky way. The silver ring on the photos is of a slightly different version with an inner diameter of 22mm, it can be found here: http://shpws.me/CEvn
