The r&p focusers on both my Parks newts have a screw in extension tube between the eyepiece holder and the focuser barrel.
Is the above statement the reason for this?
I've never known why their there. The Parks are supposedly designed for imaging ,given their age I'd say for film though not ccd.
Can anyone shed some light?
