Astrotracer

The K-1 includes built-in GPS and an electromagnetic compass, giving it the kind of location awareness that you'd usually only expect from a smartphone. The camera uses this, in conjunction with its image stabilization system, to offer the Astrotracer feature that Pentax developed back in 2011. This uses the GPS to work out where the camera is and hence how much the Earth's rotation will affect the apparent position of the stars overhead.

The camera can then shift and rotate its sensor during a long exposure to track the relative movement of the stars so that they appear as points, rather than trails, in the resulting image. Since this inevitably blurs static objects in the scene, it is most useful for creating low noise starscapes. Night time landscape photographers will also find this tool useful if they combine images with the Astrotracer on and off, using appropriate masking techniques. (Image courtesy of Pentax)
