A friend of mine has the 12" Lightbridge made life easier for himself...after the first spot-on collimation he then labeled the the truss positions against the mounts on the top and bottom sections...then just a matter of a slight tweek after re-assembly..if necessary..
As with any locking screw on either the primary or secondary mirror cell..please be careful not to overtighten..just a slight nip-up will do..
Have fun..and welcome to IIS a1120028!
