Abstract

I show the optical design for a wide-field sky camera of two meters aperture diameter. It has much better performance than existing cameras and can be diffraction limited over a field of view of two degrees diameter, and over a wide range of wavelengths. I point out the problems of implementing such a high performance optical system. I discuss how it might conceivably be exploited, for example, by using more than one adaptive optics system.
