Without tools, collimation of these is relatively difficult. I would think that looking down the focuser to collimate would be very rough. What you have done with Als col aid at the moment is center the secondary under the focuser, which is a good start.
I wouldnt use CCD inspector to collimate either, I find the results are too variable.
What you should see in the secondary when it is perfectly collimated is the main mirror and its clips, the reflection of the secondary mirror as a concentric circle and your eye.
