Here's a drawing (thanks Charles!) from a Baltimore Class cruiser After Air Defense Station that shows an "Illumination Corrector" perhaps mounted to a board. Adjacent to it is a 2'x 2' chart table and a pelorus. Does anyone know what an outdoor "Illumination Corrector" is - probably something to do with the gunfire control system. I will continue my investigation.

Just a guess, but in WWII they used star shells to illuminate the enemy at night. There were star shell control panels in the directors and elsewhere to calculate the firing angles.
