The astrotracer function is rather whizzy.
"The O-GPS1offers the advanced PENTAX original Astrotracer function,*
which works with the PENTAX Shake Reduction (SR) system on select
cameras for tracking and photographing celestial bodies. The unit
calculates the movement of stars, planets, and other bodies using the
latitude obtained from GPS data and the camera’s alignment data
(horizontal and vertical inclinations and aspect) obtained from its
magnetic and acceleration sensors. Then, the unit shifts the camera’s
image sensor in synchronization with the movement of the object(s).** As
a result, stars and other bodies are captured as solid points rather
than blurry streaks, even during extended exposures. The unit also
simplifies astrophotography by requiring only a tripod and eliminating
the need for additional accessories such as an equatorial telescope."
Dave Savage does night Nikon photography, doesn't he? Now he may have
yet another reason to consider going back to Pentax...
The above is humorous remark.
