Just guessing here - the brightest "star" was probably Jupiter. If you can focus on the Moon, that should be much the same focus position as the stars (and Jupiter).
Focus up again on the Moon - especially on the edge, then move to a not so bright star this time - sort of moderate. Does that seem to be a pinpoint of light? If you adjust the focus, does it come in and out of focus? What are the focal lengths of the eyepieces you are using?
Would you post the link to the site with details of the scope so we can look at the specifications? 6" 750mm fl - I suspect it has an inbuilt barlow lens which affects how it performs and on collimation.
But, you are under way!!
