Of course it does!
Otherwise even with a 16mm after 1 minute the stars would have a vertical trailing.
I have done many Milky Way time lapses with my previous body (KP) from the Pyrenees and the stars move not only horizontally.
Near the same location (Toulouse) I tried Astrotracer Type 3 and after 1 minute the stars are dead sharp.

I have purchased the KP and now the K3-III for their astrotracer feature, for Mliky way photography.
I use mainly the famous Sigma 18-35mm f/1.8.
The images with astrotracer at 30s or 60s are dead sharp (except on the 15% right side). Much better than stacking images without astrotracer.

Originally posted by MossyRocks That I don't know but I would think that type 3 astrotracer would struggle with a lens like that as even type 1 would mess things up in the corners. As far as the tree in the shot it may throw it off as any trails that enter or exit the tree would be truncated leading to it calculating the wrong amount of tracking needed.
Even there I am just guessing as I haven't tried that as with short lenses like that I just shoot untracked and let sequator do the stacking and freeze the foreground and background.
I have tried yesterday, the Astrotracer Type 3 works even with the earth in the frame (16mm, a hill in 15% of the image)
