Attach your smartphone to the monocular by placing your phone in the Starscope Adjustable Phone Mount and adjusting the width with the horizontal knob.
Next, adjust the camera to line up with the circular opening of the Starscope Adjustable Phone Mount and turn the side knob to fix the phone’s angle.
Then remove the wrist strap and use the tripod thread to screw the monocular onto a tripod.
When your phone is secure, open your camera app and zoom in to eliminate any black border.
