The Grindstaff Tricolor Photometer (GTCam)

Funded by the National Science Foundation and The College of Natural and Applied Science at Missouri State University.
With thanks to Daisuke Kuroda (who provided the plans of the tricolor cameras developed by Tokyo University), Kenshi Yanagisawa and Shogo Nagayama (National Astronomical Observatory), and Nobuyuki Kawai (Tokyo Institute of Technology).

The original tricolor cameras were developed using a Grant-in-Aid for Creative Scientific Research (14GS0211) from the Ministry of Education, Science, Sports, Culture and Technology of Japan.
