ASTROTRACER
Effortless tracking and capture of celestial bodies using the SR mechanism
When the optional O-GPS1 GPS Unit is mounted,* the PENTAX KP captures beautiful images of celestial bodies without the aid of an equatorial platform. Based on the data obtained by the GPS unit, it calculates the movement of celestial bodies with great accuracy, then shifts the image sensor in synchronization with this motion. Since it captures stars without a streaking effect even during extended exposures, you can record faint stars as point images.
* The GPS unit must be calibrated before shooting. Click here or consult the operating manual for detailed calibration steps.
