Arriba I live near Madrid 🙂
Anyway, when I refer to the meridian, I mean the meridian in the sky, not the line of 0 longitude on earth that runs from the north pole through Greenwich to the south pole.
When using the SeeStar you should image objects that are close to the sky meridian meaning the line from the north celestial pole through the zenith to the horizon. That of course is for the northern hemisphere.
