We have obtained unprecedented data of the southern sky, attaching the 3-band simultaneous infrared camera SIRIUS on the 1.4-m telescope constructed at South African Astronomical Observatory.We first compared the mass functions of the star-forming regions such as W3 and NGC7538 with the newly obtained southern star-forming regions in the first publications. Next, in the Lupus dark cloud, we obtained infrared images down to very faint levels, and found a shining nebula in the near-infrared. We concluded that the nebula reflects the background starlight ; the size distribution of the dust grains should stretch to fairly large sizes, which constrains the evolution of the dust grains in dark clouds.In the star-forming region S269, we found a large number of infrared sources.From the survey of the Vela giant molecular cloud, we discovered an extremely dense cluster of young (2-3Myr) stars. It has an about 0.5pc radius and at least 350 stars, with the heavier stars toward the center. We surveyed M16 and M17, where high mass stars are forming, and also the star-forming regions Chamaeleon and Ophiucus.The Great Attractor region was also surveyed for the galaxies behind the Galactic plane. The survey of the 30-arcmin region abound the radio galaxy PKS1343-601 produced several dozens of galaxies, but the number of them is far from a rich cluster of galaxies.

我们通过在南非天文台建造的1.4米望远镜上安装3波段同步红外相机SIRIUS，获得了前所未有的南部天空数据。我们首先将W3和NGC7538等恒星形成区域的质量函数与第一份出版物中新获得的南部恒星形成区域。接下来，在狼疮暗云中，我们获得了非常微弱的红外图像，并在近红外区域发现了一个闪亮的星云。我们得出的结论是，星云反射了背景星光；尘埃颗粒的尺寸分布应该拉伸到相当大的尺寸，这限制了乌云中尘埃颗粒的演化。在恒星形成区S269，我们发现了大量的红外源。从船帆座巨星的巡天来看分子云中，我们发现了一个极其密集的年轻（2-3Myr）恒星星团。它的半径约为 0.5%，至少有 350 颗恒星，较重的恒星朝向中心。我们调查了 M16 和 M17，那里是大质量恒星形成的地方，还调查了变色龙和蛇夫座的恒星形成区域。还调查了巨引子区域，寻找银道面后面的星系。对射电星系PKS1343-601的30角分区域的巡天产生了几十个星系，但数量远未达到丰富的星系团。
