Lunar disk luminance effects on manual sighting accuracy of space sextant using simulated lunar and stellar targets.The simulated sighting targets consisted of a +2 (visual) magnitude star and a simulated moon (approx 1/2Ad diam). Four values of lunar disk luminance (6.73 X10-4, 6.05X10-3, 8.84X10-2, and 0.252 cd/cm2 ) (2, 1 8, 263, and 750 ft-L) were used with four sighting ...
