Knife Edge Focuser
Knife Edge Focuser
I wanted a Knife Edge Focuser that I could install and de-install rapidly from my second camera without using scotch tape or super glue. I had the idea of a support that attach to the tripod hole of the camera.
Since an image worth a thousand words, lets browse the images below to have a better idea of this very simple design. The pressure arm have a special shape to be more rigid horizontally.
