| • | Problem |
|||||||||
| – | The
image quality is not stable - the PSFs correlate with |
|||||||||
| position
angle. There is a phase lag of about 90 degrees |
||||||||||
| depending
on which direction you are rotating. This |
||||||||||
| strongly
suggests that the changes in image PSF are |
||||||||||
| related
to the moving element in the camera. |
