one shot wonder at 30s iso800

And a very good one too. Take say, 20 the same one after the other and stack them. Afterwards, StarTools will develp it beautifully -and get the stars pinpoint if you like-. HTH

Any of the bright stars are suitable for focus.

I don't know what telescope you are using, but there should be a nut at the back of the focusser that you need to tighten.  

Refractor or Newtonian's normally have something like this, the focus lock is where the red arrow is.  No idea if you can lock Cassegrain/SCT  scopes.
