Your problem might not be guiding related yet.
No matter how good your guiding is, if your polar alignment is far off, your stars will be terrible.
A good test: don't do any guiding. Point the scope somewhere (globular clusters work well) and begin sidereal tracking. Take a 10sec shot. You should have minimal star elongation. If elongation is high, then it's obviously not guiding that is your issue. Maybe try a 20sec exposure as well - elongation shouldn't really be present if your polar alignment is good at this exposure time either.
