ASTRO: Palomar 11 A Colorful Globular
Palomar 11 (Pal 11) is located in Aquila about 47,000 light-years from
us and 27,000 light-years from the center of the galaxy. It was
discovered by George Abell in 1955 on the Palomar Observatory Sky Survey
plates. It is rather bright with a magnitude of 9.8. Reports show it
being seen in an 80mm refractor though another note says it was seen
with direct vision only occasionally in a 6" scope. One paper puts its
age at 10.4 +/-0.5 billion years.
There are a few galaxies in the image. Only one has redshift data. It
is 2MFGC 15113 at 590 million light-years. It is on the left edge near
the bottom. 2MFGC means it is in the 2 Micron Flat Galaxy Catalog so
look for an edge on needle galaxy half off the image though the core is
just on the edge.
