Short Object description:
The globular cluster M 69 in the constellation
Sagittarius was discovered by Charles Messier on August 31, 1780. It is located
at a distance of 30,000 light-years, seen from Earth 2,000 light-years "behind"
and 5,200 light-years south of the galactic centre. The diameter of M 69 is
about 60 light years, corresponding to an apparent diameter of 7 arc minutes in
the sky. At 3'' (FWHM), the seeing was not outstanding.
A very detailed image of the cluster's centre was
taken with the Hubble telescope and can be found on
spacetelescope.org. |
