13. Adjust FOCUS knobs for best image.
14. Correct lens astigmatism by adjusting STIGMA/ALIGNMENT knobs X and Y
knobs for best image.
When the astigmatism is out of adjustment, the image will be "smeared". Round
objects will appear oblong. Adjust STIGMA/ALIGNMENT knobs X and Y so that
this "smearing" is minimized.
15. Repeat (14) and (15) until best image is obtained.
16. In some cases the initial focusing done in (7) would not have produced a quality
image suitable for the alignment in (9) to (13). If this was the case, after (16) go back
to (9) and repeat the process.
