Collimation has 3 steps, and I'll identify the tools to do it:
1) centering the secondary under the focuser
Tool needed: Sight tube or Combination sight tube/Cheshire
2) aligning the focuser axis with the primary by adjusting the secondary tilt and rotation
Tool needed: Sight tube, or combination sight tube/Cheshire, or collimated laser, or autocollimator
3) aligning the optical axis with the focal plane by adjusting primary mirror tilt
Tool needed: Cheshire, or barlowed laser
I'll mention tools I have experience with and can recommend for each process:
1) Astrosystems Light Pipe
2) Astrosystems Light Pipe, Farpoint laser, Howie Glatter Laser, Astrosystems laser, Farpoint Autocollimator, Catseye autocollimator
3) Farpoint Cheshire, Catseye Cheshire, Astrosystems Light Pipe, Howie Glatter barlow attachment, Howie Glatter Blug, Howie Glatter Tublug, Astrosystems laser with barlow attachment,
Note: as long as it is barlowed and the screen is before the barlow lens on the return of the beam, any laser, no matter how bad, will work for this process.
The Astrosystems Light Pipe does it all, but, like all passive tools (including Cheshires and autocollimators), requires light to work.
Lasers provide their own light, so work in the dark.
Personally, I always collimate in the light of the late afternoon, so I prefer the sight tube + Cheshire + autocollimator processes.
If I check collimation in the dark, I use the laser + barlowed laser processes, but that is not very often.
