Hi Jacob

Using the Tak is best used for collimating the Primary mirror.

But first, do you have a tilt ring? If you don't its better to get one as it will square your focuser with the secondary mirror,

Do you have a good laser collimator? You need to use one to square your focuser and change your secondary mirror.

This is my method.

1) Align laser to center dot using the tilt ring
2) Align laser so the beam comes back on itself on the secondary.
3) Use Tak so all the circles in concentric. You need a bright touch to see them when using the Tak
4) Repeat steps until primary is aligned.

Every time you move the primary it moves the focuser.
