Hi Patrick, I've tried a few on my Obsession and settled on a 1.25 inch Glatter with the Glatter paralizer which I found to be a step up from any of the others I tried. The Farpoint one was not bad either. But that is at F4.5 with a paracorr where the collimation tolerances get fairly tight particularly on the primary. At F5 and slower probably not as critical. When I had my 12 inch F5 dob the Farpoint laser and Cheshire worked fine. I still find a Cheshire or autocollimator the best, and easiest, tools to use for collimating the primary.
