Rear view of the 60-inch Rockefeller telescope, looking down into the telescope pit, showing the mirror cell and arrangement of counterweights. Counterweight and polar axis partially visible. South pier and partial view of RA circles visible. Lower part of the dome roof visible. Near the top of the frame the J.W. Fecker nameplate can be seen indistinctly. Two arrangements of rods and bevel gears can be seen on the right of the telescope tube, connecting to the mirror cell. This may be the early adaptive optics system devised to reshape the mirror. n/a. Extent: 1 photograph. Size and dimensions of original material: Height 24cm, width 31cm.
