Deep images in the 10 ?m spectral region have been obtained for five massive Galactic globular clusters, NGC 104 (=47 Tuc), NGC 362, NGC 5139 (=? Cen), NGC 6388, NGC 7078 (=M15), and NGC 6715 (=M54) in the Sagittarius Dwarf Spheroidal using the ISOCAM on board the Infrared Space Observatory in 1997. A significant sample of bright giants have an ISOCAM counterpart, but only fewer than 20% of these have a strong mid-IR excess indicative of dusty circumstellar envelopes. From a combined physical… Expand
