Hmmm, I think you are right.  Or at least, this is what we want to do in the `RealGalaxy` case.  One option is that I could simply add some caveat here such as "Note, we are not deconvolving for the original pixels in the `correlated_noise` model in this example."

But does this in fact just mean it's getting a bit tricky to use this sort of thing as a simple example in this case?  We haven't really covered "end user" use of `Deconvolve` much yet... My main aim is to show how to do multiple convolutions at once really, which I could do with any functions... Hmmm.
