Comet camera lowered onto telescope mount on Schmidt Telescope at Goddard Space Flight Center

New f/2 Schmidt Telescope at Goddard Space Flight Center is designed for fixed-focus astronomical observations in the presence of changes in ambient temperature. This feature is desirable in photographing comets that are close to sun and can only be observed for short times at dusk and before dawn. Design employs low-expansion CER-VIT rods to maintain spacing between 23-inch CER-VIT primary mirror and focal region assembly. Telescope will also be used to probe solar wind at remote locations by recording orientations of ionized gas components of comet tails.
