Re: ATM Stellarain & collimation/cell question

["Bob May" <bobmay@nethere.com>]

Actually, putting the knobs for the primary alignment makes for an easy job
to do the collimation of the primary to the rest of the telescope.  Even
just doing a final touchup of a very short focus telescope becomes a lot
easier at the EP when tuning out the coma error in the EP as you are able to
see exactly what you are doing rather than trying to remember what was and
comparing it to what now is.
