In science fiction secret space stations typically seem to exist inside of a nebula or an asteroid. However it occurs to me that in warfare space stations hidden in nebulae would likely be discovered by enemy scouts. (Intel is key in war, and a conveniently located nebula is the obvious hiding place everyone would scout.)
So my question is if you were looking to hide a secret space station, how would you hide it? Or to be more specific, what celestial body would you hide it in/on/behind?
Edit: In this question I am more interested in what celestial body it would be best to use to hide a space station in. You can assume soft-science teleportation style FTL if you need to in order to reach a specific celestial body, but in this case assume also soft-science detection methods to allow for the searching of vast areas of space.
The general idea is to identify what object would make for the best cover/camouflage, not to simply lose the space station in the vastness of space. (For instance dropping it light years from any solar system, hiding in the emptiness.)
