<h1> Pleiades </h1>
In his book Siderius Nuncius, Galileo published a sketch showing his map of the 
Pleiades made using his approximately 20 powered telescope with its 15 arc 
minute field of view.

Galileo's map shows 36 stars in addition to the six stars which are known as
the Pleiades.  The blue circle shows the field of view of Galileo's telescope.

This is a photograph of the Pleiades, clearly showing the thousands of 
stars which are visible with a modern telescope.  The black and white circle
shows the field of view.

In March, a contingent from the astronomy group left Houston in order to view
the Pleiades in a darker sky.  Although it was not possible to see more
than one of the 6 bright stars in the Pleiades simultaneously in the
field of view of the telescope, it was possible to see at least one
bright star and one faint star at the same time.  By slowly moving the
telescope in such a way that one of the stars in the prior field of
view remained within the subsequent field of view, it was possible to
create a reasonably accurate map of the constellation.  Using this
technique, Jessica drew a star map of the Pleiades which appears below.
