Thanks for your reply.
To Vars191: I own a LightBridge 16", F4.5.
To Lismore Bloke: Yeah, I find it that way too, much easier to achieve pin point star image with a 28mm ep. My scope comes with a Crayford focuser, it works well when the ep is there, smoothly without slipping.
So, is my problem common among my fellow star chasers out there?
