Hello Jimmy! It's actually 2 seperate sets, each containing one mesh with texture, the second with the shimmering effect; each set has a diameter of 7500+ feet, so, the total spans across 15000 feet ! :)
ah, right; perhaps u didnt know, u can resize a prim with a command on the simulator console: edit scale Object x y z..
One restriction: it can only handle a single prim, not a linked set, so u need unlink em temporarily
