• Screw the camera adapter onto the front of the lens on your Video camera's lens or your
35mm camera's lens.
• Loosen the three set screws on the camera adapter.
• Place the camera adapter over the Night Star's eyepiece.
• Tighten the three set screws to fit snugly to the Night Star's eyepiece
• You may need to focus the 35mm camera or video camera in combination with the Night Star
in order to get the sharpest possible image.
• We suggest that you find an open space to work in. Focus the Night Star so that the scene is
at its sharpest. For best results you should disable the auto focus (if any) on either the 35mm
camera or the video camera and manually focus the 35mm camera or the video camera.
Once the image is sharp, then simply adjust the Night Star's front lens to change the focus.
• An important part to remember is that you are not taking a picture of an object that is far away
from you, but you are actually taking a picture of the phosphorous screen of the Night Star
that is only 2-3 inches away.

CLEANING THE EYEPIECE

You may need to clean the eyepiece of the Night Star from time to time in order to guarantee
top performance. When you receive your Night Star you should check for dust on the eyepiece
of the unit.
First you will need to remove the eyepiece. To do that you will need to initially loosen the 2
set screws that can be found on the base. Then unscrew the eyepiece counter-clockwise to
remove it.
NOTE: You do not have to remove the set screws completely, they are very small and easy to
misplace.
CAUTION: Use only Photographic lens cleaning tissue on these surfaces. Be careful not to
scratch or smudge any of these surfaces. When using compressed air to blow dust away, make
sure to avoid inverting the can while spraying. This can cause frozen propellant to exit the can,
which can cause serious problems with the glass and phosphor screen.
TROUBLE SHOOTING:
Q: Flashes, flickers, or clicking occur while operating
S: If it occurs within the first five minutes of inserting new batteries, it is normal and the device
will resume normal operation soon thereafter. If it occurs for more than 10 minutes, contact for
service instructions.
Q: Dark spots on screen.
S: These are either cosmetic blemishes in the intensifier tube or dust particles.
Q: Screen becomes darker than at previous use.
S: Replace batteries. If problem persists, contact your dealer or other authorized service rep-
resentative for service instructions.
Q: Image not clear.
S: Adjust objective lens, and/or the eyepiece.
