The Pentax K-1 has a built-in Astrotracer. This enables the camera to follow the stars utilizing GPS data to shift its sensor during longer exposures, allowing you to shoot longer exposures without star trailing while reducing noise and increasing details. The Astrotracer does much of what a tracking mount does, but without the extra cost and weight.
I interviewed Tim Little about practical real-world applications of the Astrotracer earlier. He has now created this video to further demonstrate this remarkable feature, which you’ll find above.

A very good and comprehensive look at the astrotracer, a very nice video to watch. The only thing I would comment on is that you did two calibrations, an “ordinary” one and a “precise” one. I think you only need the precise one for the astrotracer to work properly. I’ve use the astrotracer for some years now and only done the precise calibration with good results. I would also say that one thing I like about this function compared to a regular tracker is the ability to move freely to reframe your shot, and the ability to shoot from places… Read more »
Francois, thanks so much for your comment! I’ll look into that. I had wondered about the two calibrations, but was told that this was the best way to do it although you could do it with only one calibration. But I’ll try and find out more.
Also, interesting point about trackers. Thanks again for your comment!
