Is concam the smallest professional astronomy observatory in the world?
A. Yes, we believe so. The aperture of a concam2 is about 4 mm. The entire concam fits into a large briefcase, including optics, CCD, and computer. If you are aware of a smaller observatory, please email us. We think that concam is also the simplest observatory: the only moving parts is has are its shutter, its hard disk, and its fan. And they all move in simple circles.
