Without guiding? It holds for 5 minutes without any smearing, not even a pixel? That's a good astrotracker, especially for a homemade one.

Thank you. In this case, out of 44 frames, 9 had to be discarded. The tracker is performing quite accurately; the decisive factor is the precision of the polar alignment.
