I use a similar laser collimator ( Orion LaserMate Mk2 ) for my 6” , 8” 10” imaging newts and 12” Goto dob , plus I have an Orion Cheshire. I use both , one to check the other.
Been using them for 6 years ever since I bought my 6” newt.
I also made up a V block to rotate and test the laser collimator against a wall 3m away.
Cheers
Martin
