1. Cut a hole in a piece of heavy paper [like business card paper or heavier] so the paper will fit over the locking ring on the secondary holder. This is to protect the corrector for step two and three.
2. Snug the corrector lock ring by hand then rotate the secondary using the three collimation screws for leverage until the primary is centered in the focus tube. A pinhole cap in the eyepiece holder works well for this. This is not the most precise way but will get you close. There are better techniques for aligning the secondary in some of the LXD forums.
3. Take a channel lock pliers and put tape over the ends to keep from marring the corrector lock ring and gently grip and snug the secondary locking ring. DO NOT OVER TIGNTEN. Recheck that the secondary alignment did not change. You may have to hold onto the three alignment screws while tightening.
This should get you back in the game.
