Neopets: Star Mapper?

Ok, so on the Altador Plot quest, to get to the next step, you need to locate the constellation of the six stars. I really am very clueless about the whole thing and when I put in my star coordinates on a star finder it asks me what constellation (dreamer,sleeper,farmer,etc.)???? Please someone give me good and descriptive intstructions??? Please, I'm pretty lost.
