This new star stream mode sounds great, combines a foreground shot with multi shot star trail and all in camera, see below

Astrophotographer-Friendly
While the K-1 is not marketed as a camera specifically designed for Astrophotography, it certainly deserves to be.
Thanks to its built-in GPS module and the Shake Reduction system, the K-1 can track the motion stars for up to 300 seconds (Astrotracer mode) without the need for external accessories.

In addition to standard intervalometer and composite shooting modes, the K-1 also introduces the Star Steam mode, which can progressively stack star trails on top of a well-exposed foreground image.
Star Stream mode
When used properly, this feature can completely eliminate the need for post-processing software to create good star trail photos.
Finally, the utility of the K-1's LED illumination cannot be overlooked while you're out shooting the stars in a remote area. Swapping lenses, changing settings, or inserting a new memory card should be a breeze.
