Paper Abstract

The Sunrise observatory consists of a one-meter solar telescope operated in the gondola of a stratospheric balloon. The first two science flights of Sunrise have shown the unreached imaging quality at lower costs than satellitebased missions, as well as a general problem of balloon missions: Micro-vibrations have occurred during parts of the observation time and made the determination of the point spread function difficult. This paper introduces an adaption of deconvolution from wave-front sensing (DWFS) as a possible solution. The case of vibrations in the common path is verified in simulations. The utilization of high-cadence spectro-polarimeters is approached in order to extend DWFS to non-common path errors at the scientific camera.
