The trailing will be less intense when pointing the camera more into the direction of the celestial poles.
In the screenshot you see a calculation I did for the Canon R5 with the RF 15-35mm f/2.8 lens at 15mm. I kept the minimum declination at 0 for the celestial equator and activated the accurate setting. With the resulting shutter speed I can now be sure to get pin point stars in any direction, because by setting the minimum declination to 0 I basically calculate the worst case with the longest trails. The trailing will be less intense when pointing the camera more into the direction of the celestial poles.
