The Galactic globular cluster M15 is renowned for housing the high luminosity X-ray source X2127+119 which has been identified with by far the most luminous optical counterpart (AC211) of any galactic low-mass X-ray binary. X2127+119 was classified an Accretion Disk Corona object, and yet it also exhibits Type 1 X-ray bursts. This was explained when ACIS (White and Angelini ApJ 561, L101) revealed that there are two bright X-ray sources, AC211 and (2.7 arcseconds away) X-2, which is presumed to be responsible for the burst.
Here we present Chandra HRC-I images of M15 where the two central sources are clearly visible. In addition, the high spatial resolution of the HRC allows us to show that there are numerous low-luminosity sources lurking in the core, one of which we have identified with a dwarf nova in archival HST images and one which has been associated with a planetary nebula.
