easier with a cheshire sight tube, or direct with star test/alignment
try this - Since the primary is adjustable you still do it in the same order. And it has to be the holographic laser (one that projects the crosshair pattern).
Stick it in the focuser/visual back (I like to use the laser's 2" adapter and a screw-on 2" VB but you don't have to). If the cross-hair laser pattern is directly centered in the secondary its good otherwise you need to adjust the primary to center it (unlike an SCT where you adjust the corrector plate position with shims to center it).
After that its the same making sure the reflection of the center laser dot hits the center of the laser (looking thru the side cut in the laser after getting them both coexistent looking thru the corrector back to the laser while adjusting the Rumak secondary if needed).
