Abstract
The National Solar Observatory at Sacramento Peak is developing adaptive optics (AO) for solar astronomy. We are currently implementing a low order adaptive optics system that will correct approximately 20 Zernike modes. The system design permits future expansion future expansion to about 80 Zernike modes. We are using a correlating Shack-Hartmann wavefront sensor. Since a point source is generally not available on the sun, wavefront tilts have to be derived by applying correlation techniques to images of extended objects, such as granulation, probes and sunspots.
