An optical test of the space shuttle overhead windows was performed to determine how the overhead windows would affect the resolution of in-cabin telescopes such as the Spaceborne Direct-View Optical System SpaDVOS. The test consisted of four subjects viewing a resolution target through the windows with a telescope composed of the SpaDVOS objective lens and an eyepiece. Data were recorded for three focal lengths, five aperture settings, and nine windows conditions. The results showed the effect of the windows on resolution was not significant at apertures less than approximately two inches. However, the windows did degrade performance for the larger aperture settings. A photographic test and an independent visual test performed by the Aerospace Corporation corroborated these results.
