When doing the star alignment you only need do a 2 star one, unless your
cone error is large[look up cone error if you need to], in which case a 3 star one helps counteract that. I strongly recommend that you Google DARV and
watch the short tutorial, definitely much quicker than traditional drift aligning,
which, if you are looking for really accurate PA, can take quite a while, a
painstaking business.
