How to get directions in deep space?

A spaceship crew, during their interstellar travel loses control of the spaceship for a few hours due to external factors (exact factor not important). This causes the spaceship to deviate from its original course. The deviation is sudden and large (imagine the spaceship spinning(?) in space during deviation).

The question is, once the crew stopped the spaceship from spinning, how are they going to re-orient it along its original direction? What reference points can one use in space?

I think one cannot use distant stars as reference points since we only know stars by their geocentric coordinates. So, is there anyway for my space travellers to save themselves or are they doomed??
