The focusers on Skywatcher Newts are all the same, so the problem must lie with your adjustable adaptor. Mine is not adjustable, On mine when "A" is screwed into "B" the distance from the open end of the chrome
plated tube to the lip inside "B" that the eyepiece butts up against is 60mm. What is that dimension on yours when it is adjusted to it's minimum length? Alternatively you can as you said earlier remove the
tube from the focuser and screw the open end of "B" directly onto the
focuser; this brings the eyepiece much closer to the focuser.
