That is what I have read. I am not an anuthority on this.

You are right, my first collimator did that (Orion something about $85). At the time I assumed it was just it rotating within the focuser, never even considered the collimator to the out of collimation! Now I have a Glatter and don't look back.
For a while I was using the Collimation Cap but my eye sight makes it very difficult, while it isn't terrible I cannot do it without my glasses which are terribly intrusive
