Stars and other objects
The A3 main sequence star zeta Sge (5.00 mag) has a 9th
mag companion. Small telescopes can resolve this pair.
WZ Sge is a nova which lightens up from time to time from
15th mag to 7th mag. It has been observed twice in this century:
in 1913 and in 1946. Further outbursts may occur at any time.
In binoculares and small telescopes the globular cluster M71
appears as a misty patch of a sperical shape. Although it is
nowadays classified as a globular cluster some authorities still
refer to it as open star cluster. See the Messier database for
details.
Mythological Background:
Sagitta is thought to be the arrow shot by Hercules as
he is hunting the two birds, Aquila and Cygnus. But it seems that
the had luck and escaped.
