Experimental barlowed laser collimation tool. Search for a full thread on this method.
Does not require for a very precise and expensive collimation tools.
This works as the second step to collimate the primary mirror.
[1.25" tube] <- [This Tool] <- [1.25" 2x Barlow] <- [laser]
It requires a small piece of paper printed with concentric ellipses so that it will be easier to check for the diffraction rings reflected back from the primary mirror center mark.
Also here you can find an end tube cap that I use to calibrate the secondary mirror if necessary. It makes it easier to observe the mirror clips and the secondary mirror tilt. Tested on Skywatcher 250P.
