Try lowering the head a little bit to line up with the lower half of the pupil.
See if that helps...the rings I haven't seen before so I would probably call in
service to check calibration.

Subject: [optimal] Subpar Zeiss Clarus AF Images
We are slowly learning to use the Clarus 500. The color images are superb and
typically without artifacts.
The green FAF images, however, are not up to par as almost every picture
displays a series of dark concentric rings in the periphery along with uneven
illumination, nasally and temporally.
Because of our relative inexperience with this instrument, we don't know if the
cause is operator, patient, or equipment related. What do you think? How can we
eliminate these unwanted artifacts.
