The bright but very sparse star cluster Messier 25 in Sagittarius, shown in an R-band CCD image obtained with the UA 16-inch telescope. The field of view shown is 20 by 30 arcminutes in extent. This is a big cluster - it spreads off the northern edge of this view.
M25 is in the rich Milky Ray region toward the galactc bulge. We see it about 7 degrees northeast of the Trifid Nebula and 4 degrees southeast of the Omega Nebula.It is also notable for including the Cepheid variable U Sagittarii - seen as the very bright star near top center in this picture.
