Abstract

Progress on the German large telescope project (DGT) since 1988 is described, with emphasis given to advances in mounting design and important manufacturing aspects related to segmented optics. The two segmentation possibilities, various polishing methods, focal tolerance considerations, and control of the segmented primary for the DGT are set forth, and the Hexa-pod mounting design and dome structure are mentioned. Site selection, funding considerations, and the possibility of an international consortium to continue the project are listed as issues still to be addressed.
