M19 is a fairly large and somewhat concentrated globular cluster that
is about 65 light years in size and is approximately 22,500 light
years distant.
M19 was easily visible in the 5" f/5 finder scope.  Through the 17" at
144x it appeared as oval shaped with 2 bright outlying stars and was
partially resolved.  Increasing the magnification to 259x resulted in
a beautiful view of a fully resolved globular cluster.  A line of
faint, almost equidistant field stars was noted to the west of M19.
