This cluster is perhaps a former member of the
Sagittarius Dwarf Elliptical Galaxy (SagDEG), or
Sagittarius Dwarf Spheroidal Galaxy (Sgr dSph), the nearby dwarf galaxy
discovered in 1994, which is currently in a close and perhaps final encounter
before its tidal disruption, with our
Milky Way Galaxy.
The image on the right was obtained by
Chris and Dawn Schur
from Payson, Arizona with their 12.5" f/5 Home made Newtonian and SBIG ST8i
NAGB CCD camera with enhanced cooling. This is an LRGB composite image,
exposed LRGB = 80:20:20:40.
