Abstract

Because of the very small size of the isoplanatic patch resulting from high altitude, tropopause seeing, the use of the Solar Differential Image Motion Monitor (S-DIMM) for solar seeing observations at large zenith distances is significantly compromised. I examine the resulting limitations and attempt to correct for these in its use for the Advanced Technology Solar Telescope (ATST/DKIST) site survey. Suggestions are given about how one might correct for this altitude seeing by Dual Conjugate and Multi-Conjugate Adaptive Optics (DCAO/MCAO). I also comment on adaptive optics for corona observations with the use of Laser Guide Star aided wavefront sensing.
