Yes, I've read about the battery issue. It sounds like it draws battery even when it is off. I've got rechargable AAAs, so I will just plan on starting with a full charge any time I plan on using it. I haven't heard anybody say that they run out before a night's session.
I have a theory that the "precise calibration" can be pretty important and I have a plan to make mine VERY precise. It involves turning a bowling ball into a large ballhead for the "precise calibration" process. I plan on experimenting with the amount of time to move in each axis (you have up to 20 seconds for each of the three axis). I have the feeling that a lot of people do it too fast or inaccurately. I've also heard that people got better results when they upgraded to the latest camera firmware. My "hero" with the O-GPS1 (and a K-5, now K-5 iis) is a frenchman, Stéphane Poirier. His stuff is amazing. http://poirierstephane.free.fr/photos/index.php?/category/132 They are made from a "stack" of shorter exposures. He uses the DA* 200mm f2.8 and says that the O-GPS1 will give you 30 sec to 1 minute exposure times with that focal length (depending upon the declination of the object).
