Ok here is the fool proof instructions that you need.
Lay your scope down on say something like the lounge or kitchen table with some cushions to prevent it rolling. Next remove one screw from the secondary and then install one Bob's knob. Make sure it is firm but not too tight. Finger tight is fine. If you are unsure of whether the screw is in, slightly pull the knob. If it comes free then you have not screwed it in far enough. Make sure each knob is finger tight.
Once you have the first Bob's knob in position then unscrew another screw and install the next Bob's knob. Make sure once again that the knob is firm and screwed in.
Follow this until you have all three knobs in place. One thing you must not do is undo more than one screw at a time. The screws hold the secondary assembly in place.
Now for quick collimation.
Using a piece of A4 white paper put a hole in the centre that you can peep through. The hole only needs to be about 2-3mm in diameter. Now holding the paper up in front of your face and standing back from the front of the OTA around 2-3m (you need to be far enough back to see all the reflections and you will know when you see them) line up all the reflections. All the circles have to be concentric, so you need to move the Bob's knobs until you get them all concentric. Make sure you loosen two off slightly before tightening another.
This might take a while to get everything concentric, so take your time. Once done though you will need to do a star test to get the final collimation correct. The screws must always be firm and not loose throughout the collimation process. Do not over tighten the screws either, you can damage the assembly.
And that is basically it.
