Astrotracer Effectiveness?
Also if you're using a manual lens the focal length setting needs to be accurate.
Which lens were you using?
I once had a similar problem and the issue was traced down to a faulty tripod head.

I was using the D FA 28-105 and also a Tamron 17-35, neither of which are manual lenses.

Before anyone asks, the precise calibration was successfully completed before taking the shots and my camera has no fault with the sensor shake reduction mechanism.
I think the tripod head needs looking at. These lenses aren't really heavy but neither were the DA50 and Tak lenses that I noticed the issue with.
I think SR is automatically turned off, I've never actively changed the setting when doing astro.

Another option would be to check the astrotracer batteries if it has been stored for a while.

They did a review of built-in Astrotracer v external unit. This and subsequent 'chat' might give you some clues.
1. Astrotracer was definitely on and showing as operational, after performing the precise calibration
2. SR is automatically 'off' when using the 2 second delay, which is what I was using on the night, but I would have thought that Astrotracer ignores this?
3. The star streaks were across the entire frame, not just in the corners
Does anyone else have any ideas?

Thanks for all the feedback so far, I'm not sure we have found the source of the issue, but some avenues are there to go down. I can confirm the following:

I have the same problem. I have a k3ii with build in gps. I tried everything maybe 50 times. Calibrating, recalibrating, changing location. Doesn't matter if I use the tripod or directly puttin on the ground facing up. I use an external intervalometer to not shake the camera at all. Astro tracer is on, calibrated. Tried 1 minute exposure at 55mm. After that I am turning off the astrotracer with the green button and exposing for 60 second. Identical results and Identical star trails. I also realized that star trails normally should look like straight but both of pictures have identical arch looking weird star trails. Have you figured it out what was the problem.

Just a quick query from me, I was out the other night with my K-1, using the Astrotracer functionality for night shots. Exposures were between 30 and 50 seconds, on a sturdy tripod. I took one shot without the Astrotracer and one shot with it, for each composition. When reviewing the images on my PC the trails of the stars looked identical with or without the Astrotracer! Has anyone else noticed this, or has anyone got any observations on the effectiveness of the Astrotracer?
