The document describes how to take microscope images using a mobile phone. It involves: 1. Holding the phone 10cm from the eyepiece and identifying the pinpoint light. 2. Turning off the flash and framing the pinpoint light on the phone screen. 3. Forming a ring with thumb and index finger around the eyepiece for support. 4. Slowly approaching the lens to the eyepiece while keeping the light framed, until the microscopic field is visible. 5. Pressing the phone firmly against the finger ring to take the picture, ensuring no external light enters.
