Stargazing and Enlightenment

[Rei]

How do I get this achievement?

[HoHoHO]

For stargazing in taoist sect, find the drunkard at the stargazer location at night. Just meditate and he'll pop up at midnight there for a cut scene. He wants to visit somewhere. Invite him to party, go there, and then listen to what he says. Afterwards he'll tell you to go back to sect and look at the sky 5 times at night and you'll get the achievement.

Oh I have to be part of the Taoist sect?

I believe you do, because you need to defeat the sword formation as part of the quest.
