thank you, yes, excellent point there. A mistake I find myself making if I'm not paying enough attention. The (wrong) instinct is to tighten it until you find yourself grunting with the effort.
Even with the slightest tightening, tho', my donut moves off the center mark of my barlowed laser collimator.
Cheers

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!
