Paper Abstract

This paper describes the engineering steps taken to obtain best imagery across the field at the R-C focus of a 4m f/2.65 primary in combination with a secondary giving a final f/8 beam. Real life constraints, such as limited initial information, time available for testing, and manpower available, point to the importance of some factors which tend to be overlooked during the early mechanical design and optical manufacturing stages, as well as during the initial assembly of the telescope. Some of these factors are listed so that others may succeed in an operation which most likely will be performed under adverse conditions.
