My Laser Collimator arrived today. It was one of the cheaper ones from Amazon and was £26.99 so it is quite a lot cheaper than the average £40 - £50. It is really good, had my telescope collimated in 2 or 3 minutes and it can be done by one person, first class indeed.
"Seben Laser Collimator LK1 31.7mm (1.25")"
An excellent investment!

Just check that the laser is itself collimated. (Point stationary when projected against a wall >10 feet away & the device is rotated about its axis) Many aren't, and if they are out a laser collimator is a very fast, convenient way of ensuring that your scope is out of collimation.
Collimation by direct observation of a real or artificial star under very high magnification (x80 per inch of aperture is about right) is the best, in fact the only, way to get the thing absolutely spot on. A Cheshire eyepiece or laser collimator will get you close, quickly, but not get the final tweak which is the difference between a good and a really great view of the planets when the seeing is steady.

Thanks for that Brian. I rotated it while it was in the eyepiece and it was out a little so a couple of tweaks later and job done. Seems spot on now.
