Installing the Iris Diaphragm
1. Remove the viewing head by loosening the allen screw that secures the head to the
optical body.
2. Use caution to hold the viewing head as you loosen the screw so it does not fall.

place.
4. Mount the eyepiece tube on top of the iris diaphragm and tighten the allen screw to secure
it into place.
Operating the Iris Diaphragm
The iris diaphragm is used to enhance the contrast of the image and provide additional depth
of field for photography. To open the iris diaphragm move the adjusting lever to the left, to
close the iris move the adjusting lever to the right. Do not close the iris diaphragm too tight or
it will reduce the resolution.
