Re: [ATM] Refractor baffling

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

Simple.  Draw a line from the edge of the objective to the
focuser on the same side on a plan of the scope.  Then follow the
rules for plotting a Newtonian scope baffles using that line as
the limit for incursion of the baffle to the light path.  Draw a
line from the opposite side of the focuser (input end of the
tube) to the objective and where the limit line and the crossing
line cross is where the first baffle goes.  From there, the base
of each baffle is used as the end point for the crossing line
from the focuser to determine the next location.

Replace the obvious words with the proper character.
