I use a barlowed laser and adjust the tilt plate till the beam hits dead centre on the secondary spot , rotating and adjusting till it stays centred .
Then I adjust the secondary til the return beam hits dead centre of the laser , So now you are physically aligned.
Then all you need to do is ONLY adjust the primary at night on a defocued star till its concentric and you should be good to go .

Sounds like a plan. Can you adjust the primary on these scopes?
