Re: Is this tilt in the image train?

Yes I have noticed this myself. Stacking the images usually reduces the abberations.
The direction of tilt shown by CCD inspector is the same as before. I wonder if the new ap mount is now more accurate now that the stars are more steady. 
Before I would have 0.7,-0.8 arc sec RMS tracking, now down to .25.
