View Full Version here: : Collimation laser sloppy fit

The sloppy fit is making repeatable alignment difficult. As the laser is tightened in the eyepiece housing it moves and can position the red dot in a different place each time.
The laser has been collimated so the dot is not moving when rotated in a Vee block.
I have added tube to the laser but the focuser still permits sub optimal results, guess I star test and adjust.
Anybody have a better solution?

Try putting a wrap of masking tape around the collimator sleeve and add some more tape if still loose or take some tape off if a little too tight.

There are self centering adaptors you can buy. Like this one:
