Madrigal Imaging MP-9 - Manual (Page 29)

Step 22 ➤ On the MP-9, tighten the three bolts
labeled “D”.
On the MP-8, tighten the two bolts labeled “D”.
Step 23 ➤ A green image is displayed. Loosen the rear wing nut on the
green lens and slightly defocus the center of the picture.
Step 24
➤
On the MP-9, locate the two
adjustment bolts at the upper
right corner of the green lens
mounting plate (viewed from
the front). Adjust the two bolts
until the top and bottom areas
of the picture are equally defocused. Use the following technique for the
adjustment: Turn the SIDE bolt
1 ⁄ 8
turn CCW. Turn the TOP bolt about 1 ⁄ 8
turn CW until it stops. If defocus at the top and bottom are equalizing,
repeat until equal. If the top and bottom are not becoming equally defo-
cused, use the same technique but instead turn the TOP bolt CCW then
turn the SIDE bolt CW until it stops. Repeat until defocus is equal.
On the MP-8, adjust the
large allen head bolt located
at the upper right corner of
the green lens mounting plate.
Turn the bolt head until the top and bottom areas of the picture are
equally defocused.
NOTE: On all models, it may be necessary to readjust the lens’ rear wing nut to
keep the center defocused.
Step 25
➤
Rotate the green lens using the rear wing nut until the
picture is focused in the center. Tighten the rear wing nut.
If necessary, loosen the front wing nut, rotate the front lens
barrel to readjust the focus in the corners, then re-tighten the wing nut.
