You'll need one of those things that allow you to adjust the tilt of the focuser (I think it's called a tilt plate?).
First collimation task is to use the tilt plate to make the laser hit the middle of the donut on the secondary. Then use the coincentric circle hologram or tak scope to adjust the secondary. It's actually not that hard, TBH, but it does like you to be accurate.

And as mentioned above, grab a moonlite focuser.

For visual, you'll need a 4" spacer to get the eyepieces into the focal plane, but as mentioned before, it's an astrograph and you may well not need or want to go visual.

Best,

Markus
