I have been giving it some thought also to try to work out if its a balance or a flexure problem between the 2 OTA`s.?
My thoughts are setup guidescope with camera and PHD and have a illuminated reciprocal eyepiece in the other scope at high power with a star centred. Make sure you are well east or west of the meridian. Let PHD do its thing..Does the star stay centred in the other scope? Give the scope a very slight tap every now and then. does PHD pull it back to where it was or does its position change slightly every time in the same direction or is there drift in the same direction?
Now change the eyepiece and the camera around and try the same things again? does the star drift or move the same way or is it now moving the opposite way?
My thoughts are if the movement is reversed then there`s some sort of differential flexure betwen the 2 scopes but if it still keeps moving the same way it maybe some misbalance in the setup?
I`m not sure if this is right? someone correct me if my idea is mislead!
I will give this a go myself if this cloud goes away anytime soon!
cheers Gary
