The reviewers commented that a good case was made for the f/1.2Davies-Cotton design; however, the additional costs due to the longer camera arms await evaluation. Steel is the preferred structural material with possible space-frame and quad-arm cross bracing to suppress low frequency oscillations. Some wind tests can be carried out on the 10m. Further evaluation of distortions of the OSS by wind and gravity are needed in order to achieve the light imaging specifications. No recommendations for a larger OSS other than the possibility of reducing stray light through baffling. The system as presented warrants an end-to-end stray light analysis.
