source of light or at a laser, as this may cause PERMANENT RETINAL DAMAGE and may lead to BLINDNESS.
• Take necessary precautions when using the device with children or people who have not read or who do not fully understand
these instructions.
• Do not try to disassemble the device on your own for any reason, including to clean the mirror. For repairs and cleaning of any
kind, please contact your local specialized service center.

To attach a DSLR camera, you will need an appropriate T-ring and a camera adapter. Simply attach the T-ring to the camera body
and thread the camera adapter onto the T-ring. Insert the barrel of the camera adapter into the focuser and secure it in place
with two thumbscrews.
You may want to consider using a remote shutter release instead of the shutter release on the camera. Touching the camera may
shake the instrument and blur the resulting image. Also, make sure the tripod is steady.
