Well, got reply from Stellarvue. They basically said to collimate the scope. Anyway, first made sure that focuser was tight and secure... it was. Then I loosened the fastener screws on the lens cell nothing happened, released the fastening ring in front of the lens and hear something shift. WaLah! Checked the diffraction rings, not exactly perfect but much better than before. Will test it on actual star tonight...

Hope to have another CNS session somewhere soon so that I can get the Si Fu (Vincent, Sam etc) to check it out for me.

dude, if you meet up with Sam, ask Sam to use the Cheshire eyepiece to check for collimation indoors. You don't need stars to do that.

I have already told Sam how to use that collimation/cheshire eyepiece to check for collimation on a refractor.

Pls continue this discussion on collimation issues under a new thread.
