An Investigation of 48-inch Telescope Image Quality

Brian McLeod, CfA


An intensive investigation into the poor quality of images produced by Mt. Hopkins 48-inch telescope has revealed several problems including collimation drift, spherical aberration, and high order errors in the primary mirror. I will discuss the results of the investigation, and the measures that would be required to solve the problems.
