Aperture Assembly Removal

The entire aperture-shutter assembly can be removed by unplugging the shutter cables, removing the three hex head screws that fasten the assembly to the spectrograph body and sliding the assembly out. Because of extremely tight clearance, fragile wires, and delicate optics, it is requested that only qualified instrument/telescope technicians and the cognizant observers remove the aperture assembly.
