Would anyone like to comment on the usefulness/uselessness of a laser collimator for a SCT? Purchased new they are kinda pricy, but there are a few on astromart for much less. What worries me though is that every single seller comments that the collimator works perfectly and was used only once! If it works so well, then why sell? (Maybe they figure that once the scope is collimated it will remain so forever more. :smirk:)

Anyway, any comments?

No, it's because they realize that the SCT collimator didn't do anything that Polaris can't do. If seeing is even mediocre, and you take your time to continually return Polaris to the center of the field after every screw turn, then you can achieve perfect collimation without the purchase of any tools.
Bob's knobs make it easier because no tool is required.
