Thanks guys.

Dave, I do see the fringe too. Ive used it to achieve focus, the red fringe disappears through focus and a blue fringe appears on the other side of focus.
I thought it was the ED refractor... I'll have a go at rechecking focus. I try to settle at focus with the focusser on its way out.
Maybe its time for a better LPS filter. What do you guys use?
Mine is pretty old.
