The Eyelighter 2 has a variable 74 degree tilt.
With the thumb screws of the tilter facing you, set the tilt so the edge of the washer on the top thumb screw is just inside the right end of the adjustment slot and tighten the thumb screw. This will set the angle as in the original design while maintaining the ability to make tilt adjustments. This video shows Larry using the Eyelighter and the singular optimal tilt angle of the original design. https://westcottu.com/history-eyelighter-larry-peters
