5: Replace the 30mm eyepiece and try the alignment out on a target of choice, and be ready for a pleasent surprise.

Another thing that helps is to choose a second star that is quite far away from the first. These processes go to reduce error which is what most causes errors in alignment.

Mental.
Defocusing: that a good suggestion. I'll try it
