Hotech instructional video wrong ?

Howdy , I found something this afternoon , a problem with the Hotech instructional video .

If your secondary mirror isn't in the correct position to begin with then the whole process is flawed .

I've been trying to centre my secondary mirror for the last year and a half and could never quite get it there . I did it again this afternoon after inserting a field reducer into the focuser on the LX200 . Got to the same stage and still couldn't align the secondary mirror correctly .

I went through the entire process again and got to the part where LX200 users have to remove the corrector plate . I happened to glance up the tube and noticed that the laser cross hairs were way off centre of the internal tube . I thought that surely the laser cross hairs would have to be centred in the middle of the tube , right ?

I centred the cross hairs and the shadow of the tube , on the face of the Hotech plate , making sure that everything was aligned on the hotech .
I aligned the focuser and attached the corrector plate . Bingo , the secondary mirror now aligned perfectly .

Surely I can't be the only person who's noticed this , or am I wrong ?
