NGC 188 is a moderately old open cluster in the disk of the Milky Way. The exposure was 631 seconds through B1, 315 seconds through A1 and 316 seconds through B5.

47-TUC is a metal-rich galactic globular cluster. It was imaged for 1033 seconds through the B5 filter.

NGC 2808 a cluster in the Large Magellanic Cloud was imaged again for 507 seconds through A1 and 1016 seconds through B1.

Carina is a very unusal dwarf satellite galaxy of the Milky Way in that it appears to have two separate stellar populations, one which formed rather recently. This is odd because the internal velocity dispersion of Carina is so low, that the first generation of star formation should have heated the gas to escape velocity and dispersed it therefore not allowing another generation of stars to form. This exposure of 1980 seconds included both the A1 and B1 filters.

NGC 6752 is a galactic globular cluster previously observed in this mission. This exposure acquired an additional 990 seconds through A1 and B1.

1121 seconds were obtained through B1 and A1 of another field in M31

M13 is a relatively bright galactic globular cluster. This exposure was for strong> 1490 seconds through A1 and B5.

NGC 4258 (M106) is a bright and rather large spiral (major axis diameter = 18 arcminutes). This galaxy is distinguished by "anomalous arms", better described perhaps as jets, seen curving outward through the disk in radio emission and optical emission lines. Recent measurements of maser regions near the nucleus suggest a supermassive black hole (with mass of order 10^8 solar masses) at the center of this galaxy. 2160 seconds through B1 and A1 were obtained.

NGC 752 a galactic stellar cluster was observed for 1172 seconds through A1 and B5.

The Hercules Cluster of Galaxies or Abell 2151 is a rather distant (by UIT imaging standards), spiral rich cluster with lots of interacting galaxies. It is probably the most interesting cluster in the nearby Universe. A total of 1256 seconds were obtained through A1 and B1.
