   Also,  controls over encoder resolution will be provided.  These
are required only for alignment of JMI/MG-III (Tangent Instrument)
compatible systems,  and will be discussed in the next chapter.
For all other systems,  Guide just relies on the internal alignment
of the telescope,  so be sure your scope is properly aligned in
the manner described in its user manual.

   The hardware issues in connecting a telescope to a computer are
quite varied;  you should check the instruction manual for your
telescope for details.   You should determine to which COM port
the telescope is attached,  and pick the corresponding port in
the dialog box.  If you don't know which port is used,  it's okay
to guess.  The worst that will happen is that, when you try to
control the scope,  Guide will pause for about fifteen seconds,
then report its failure.

   In general,  you can just pick the sort of telescope you're
using,  select the right COM port,  and you'll be all set.  Most
telescopes will either be in the above list,  or will use the
Meade LX-200 command language (so you can just tell Guide to use
that system).  ASCOM is a system that allows a wide range of
telescopes to be controlled,  including those in the above list
plus many others.  If you select ASCOM,  you'll be asked to
select your telescope from a different (much larger) list of
possibilities.

   Once you have used the Telescope dialog to tell Guide what
sort of telescope you have and which serial port it uses,  a "Scope
Pad" item will be added to the main menu.  Clicking on "Scope Pad"
toggles display of a little floating dialog box,  loosely modelled
on the LX-200 control pad.
               
   The next step is alignment.  For this purpose,  systems fall into
two categories:  the JMI/MG-III encoder-based systems,  and
everything else. "JMI/MG-III" is used as a shorthand to refer to a
huge range of devices: the JMI NGC-Max series,  the MicroGuider III,
