Hi Malcolm,
I was assuming the secondary was correctly placed, but point taken.
I used a sight tube for my secondary, and a Cheshire ever since. I did pick up a cheap laser collimator on Ebay, but have never gotten around to using it. The one thing that I never did fathom was the thing called an Autocollimator that used to be sold as a set with the Cheshire by one company. The guy who owned it couldn't make head nor tails of the instructions, he lent it to me, and I couldn't make any sense of it either.
Cheers,
Renato
