Is this normal ?
Just wanted to check with the collective IIS wisdom about this. whenever i run calibration on my autoguider when it is close to the SCP i always get one axis longer than the other, as seen in the attached. however, when i am imaging closer to Dec = 0 deg, the length of the arms are the same. is this normal or is there something amiss ?
FYI, the X axis in this is aligned to the RA axis and the Y axis is aligned to the Dec axis
