For example, it should cope well with the few million faint stars per square degree found in Baade's Window
- a corridor of low interstellar absorption toward the galaxy's rich inner regions in Sagittarius.
Holtzman and his colleagues used the Hubble Space Telescope's wide-field camera to peer through a relatively dust-free pathway, known as Baade's Window
, into the galactic bulge.
The OGLE team has found 933 in a section of Baade's Window
(an area in Sagittarius rich in stars and relatively free of interstellar material), where fewer than 100 had been known before.
