Even with the astrotracer 30 seconds at 500mm is too long.  
Now, I need to find stacking software for my mac.

These were photographed on Empire grade at the gate for Grey Whale ranch, 
with my Pentax K-5 II, using my O-GPS 1 in astrotracer mode.  
Some were shot with John Francis' 80-200/2.8 and some with my bigma.

I learned that using a ballhead sucks for astrophotography. It is 
impossible to make fine adjustments in just one axis.  Hell, it is 
impossible to make accurate fine adjustments period.
