Abstract
The performance of low-order adaptive optics compensation for extended object is briefly analyzed theoretically. Several series of short exposure images and simultaneous wavefront sensor data at the Vacuum Tower Telescope at Sacramento Peak were collected to validate the low-order adaptive optics compensation for low contrast extended object, including solar granulation and sunspot, by using deconvolution from wavefront sensing (DWFS). The results show the low-order adaptive optics compensation is very effective for low contrast extended object.
