I'm curious about the advice on collimating, throw out the locking screws? On the primary? Why? Up grade the springs? I'm yet to pull any of that apart so a little bit in the dark ( no pun intended). I collimating every time it's always out by say 5mm I get it pretty much spot on when adjusting. What is it that keeps "miss aligning is it the primary or secondary or both? How can I find out? Is it normall for a dob to fall out of alignment every time you use it or move it? if I'm moving it 30 feet on a dolly. I'm am lifting it on and off. (If it is like tuning a guitar however once I tune my D28 it rarely needs retuning after a month of regularly playing - especially when it's a crap night)
Like to know if it's me or that's just the way it is.
