... is this the right chip to use for this purpose? ... It seems to me that, with the 9 degrees of data of the chip, it should provide consistent directional information when the scope points to the same place where the light source is, correct?
Short answer ... No.
Somewhat longer answer ...
It's got nine degrees of freedom - linear accelleration, angular velocity, and magnetic field.
Your telescope isn't moving away from your observatory, so linear accelleration isn't needed. That's three down.
When you first switch it on, you don't know where your telescope is pointed, so although this device can confirm it isn't moving, it won't tell you where it is. Three more down.
Only the magnetic field sensor can give you fresh information.
