Visually, there's not much I can think of to say about this. If you want, you could read about it, though. And then you could say, "Ah, so that is what a super-metal-rich planetary nebula looks like."
Again, two sets of data were three years apart, so if you are a very keen observer you may notice slight color fringing.
