RC8 collimation or focus problem?

Hey all,

So I just tested my new (second hand) RC8 out for the first time last night and the stars are looking a little wonky:

So I'm wondering if this is a collimation issue or a focus issue? I got the focus as close as I could. As for collimation the secondary mirror and the focus tube are both in line, the only thing I think might be out is the primary?

Any help would be greatly appreciated.
