Magnum计划的目的是在几年内对数百个活动星系核进行多色监测观测，以便使用简单的物理原理测量这些遥远天体的距离，从而确定宇宙参数。该项目得到了早期宇宙研究中心的资助。该项目于1995年开始，计划于1998年开始观测。对于这个项目，我们正在建造一个新的遥控天文台，带有一个2米的自动化望远镜，以及新的红外和光学仪器。该望远镜针对红外观测和多年来的监测观测进行了优化。我们的飞机将在毛伊岛的哈利卡拉山顶运行天文台，这是一个适合进行长期监测观测的地方。该望远镜直径为2米，有一个反方位的支架。天文台将配备自动仪器转换器、天气监测器、环境监测器和云量监测器等设施，使望远镜的自动和远程操作变得更容易。观察将使用现场调度器进行，该调度器将通过联网的远程计算机进行指挥。正在为Magnum项目建造两台天文台仪器。第一种是红外和光学成像光度计，它结合了二色性分束器，具有从0.3微米到4微米的宽波长范围内的成像能力。它将主要用于AGN监测。另一种是大视场(33‘视场)8K×8K马赛克CCD相机。
The MAGNUM Project is designed to carry out multi color monitoring observations of hundreds of AGNs over several years in order to measure the distance of these far away objects using simple physical principles and thereby determine cosmic parameters. The project has been funded by the Research Center of Early Universe. This project started in 1995 and observations are planned to begin in 1998. For the project, we are building a new remote controlled observatory with a 2 m automated telescope as well as new infrared and optical instruments. The telescope is optimized for infrared observations and for obtaining monitoring observations over many years. Our plane is to operate the observatory at the Haleakala summit on the Island of Maui, a suitable place for long time monitoring observations. The telescope is 2 m in diameter and has an alt-azimuth mount. The observatory will be equipped with such facilities as an automated instrument changer, weather monitor, environmental monitor and cloud cover monitor, making it easier to operate the telescope automatically and remotely. Observations will be carried out using an on-site scheduler, which will be commanded through a networked remote computer. Two observatory instruments are being built for the MAGNUM Project. The first is an infrared and optical imaging photometer which incorporates a dichroic beam-splitter and has an imaging capability over a wide wavelength range from 0.3 micrometers to 4 micrometers . It will be primarily used for AGN monitoring. The other is a wide field (33' field of view) 8K X 8K mosaic CCD camera.
