Yes, but, what did you think of Martin's image?

I would put my money on the idea that this galaxy's disk, far from being planar (as we would expect from the naive expositions in textbooks), is actually composed of several different rings (annuli) at various position angles.

In my view, this is also the case for the Andromeda Galaxy.

cheers,
bad galaxy man.

P.S. Radio astronomers are very accustomed to modelling the gaseous disk of a galaxy with a "tilted ring model" in which the overall galaxy is made of up several different rings/annuli at various angles to each other.
