MicroSetting

[Harry]

Good day,

I am a professional Diamond Setter, using my microscope to set diamonds, i recently purchased a camera and placed on the microscope connected to the screen. I need some help with adjusting the Ratio

I have a X 0.5 lens attached on the bottom of microscope and i need to have my setting (knob) at "2" for me to have the resolution i need to work. When i attach my camera with an additional 0.5 lens hooked to the camera. I see everything very close. I need the screen to cover the whole piece i am working on without turning the knob to 0.7 setting. Any suggestions ? . Can someone help me with this ? i can send some pictures and videos via text as i am not able to attach them here. File too big.
