I hate to disagree Gazz

I have a LB12".
I collimate the secondary before leaving home. The scope is assembled on site, and then it takes me approx 1 minute to collimate the primary.
I use the Orion Cheshire E/p from Bintel.
With the optics being the same in the LB and solid tube G.S.O's (mine are great) the other things that can be ruining the views are poorly figured primary or secondary mirrors.
The main thing is to eliminate each step as the culprit, it won't take long.
Good Luck!!
