| Abstract: |
We introduce a novel photometric system, which includes a Schmidt telescope, an objective prism, a CCD camera, and a multi-peak interference filter. Light in different passbands is differentially refracted by the objective prism, pass through the multi-peak interference filter simultaneously, and is focused on the CCD separately, so we can have multiple “images” for each object. This system enables us to monitor blazars exactly simultaneously in multiple wavebands on a single telescope, and to accurately trace the color change during the variation. We used this novel system to monitor the BL Lacertae object S5 0716+714 in 2006 January, and the initial results are presented here. |
