If a body spin to fast, it won't be able to condense into a planet or 
moon. There is a point where it can, theoreticaly, form into an almost 
pancake shape...
If it get accelerated, by some obscure mean, it can fly apart.

For the neutron star, you'll see the incandecent gaz cloud that could be 
called it's athmosphere, or have degenerated into a solid crust but 
still stay "normal" matter.
If you where to remove that outer layer to reveal the all neutron core, 
well, it may be perfectly transparent, only detectable by the 
gravitational bending of light... There is also the possibility that 
there is not enough place for the photons to squeeze through. What appen 
when a photon hit a neutron square on? There could be some reflection...
