Can anyone identify this octagonal dish piece for me? It seems like this piece would be named "Octagonal Dish 2 x 2" but I can't seem to find it on any of the usual sites. Is this named something else or is it not a real LEGO element?
I believe it's yet another MEGABLOKS part. You can see it on the top of 9321 Cyborian rover holding the yellow antenna, for example.
