Bill,
I do not know if William Optics supplies a 2mm Hex Wrench, but you will need
one. I bought several at a local hardware store in the "Little Drawers" section
for the two WO ZS 66SD I sold, and one for the one I am keeping. It goes in the
hole of the black thumb screw on the bottom of the focuser. Your instruction
manual will tell you how. But, the Black Thumb screw has to be TIGHT. Then,
using the 2mm Hex wrench, tweak the focuser to your preferance.
Seize the Night !
Pete
