Re: [ATM] Secondary Offset

> 
As I've been trying to say, normally you *will* offset your secondary
during the collimation procedure. A secondary that *looks* centred
under the focuser in a sight tube is actually offset optimally towards
the primary for the given offset away from the focuser, for exactly the
same reason (perspective) you need the offset.

     Hm Okay. Normally I sort of just eye ball it, there is no way for me to
truly center it under the focuser so I just adjust it till it looks centered
under the focuser, hopefully that is offsetting it enough.
