RC 10 collimation headaches

Thanks all for the answers.
But my messing made my mirror way off so here was my cure...
1/ Video camera facing scope (primary mirror) -luckily was a 60Da so could turn the video screen 180" to face me whilst I messed about. -Literally was so far out of kilter I had to use this method to even align basically...then
2/ Cheshire eye piece to align secondary- roughly but bloody hell it works.
3/ Tak scope to finish the job- I was not far off with the Cheshire.
I have to say it is really hard to do this alone. I did it but you would be better off getting some one to help you. And Quicker.
Star test can wait- till the snow stops me thinks!!
