图示说明:
印第安星座及其亮星和周围星座。印第安星座周围环绕着(按顺时针方向):显微镜座、人马座、望远镜座、孔雀座、南极座、杜鹃座和天鹤座。由于印第安星座靠近南天极,因此在南半球的任何地点,在一年中的某个时段都能观测到整个星座。对于北半球靠近赤道的狭窄区域,整个星座也可见,而北半球赤道其他区域则只能看到部分星座。在南半球温带和南极地区,印第安星座是拱极星座。该星座在北半球的秋季和南半球的春季夜晚观测效果最佳。
此图的 y 轴是以北为上的赤纬度,x 轴是以东为左的赤经小时数。这里标注的恒星大小与恒星的视星等有关,视星等是衡量恒星视亮度的标准。较大的点代表较亮的恒星。希腊字母代表星座中最亮的恒星。这些恒星按亮度排序,最亮的恒星被标记为α星,第二亮的为β星,等等,不过这种排序并不总是完全一致。虚线标注的是国际天文学联合会的星座边界,绿色实线标注的是用于表示星座数字的一种常见形式。星座边界和连接恒星的线条都不会出现在天空中。
