it is not the pixels ET, check my help file. (turn off after opening to see feature) not sure but maybe something similar to those cross features can be seen on so many photos taken by apollo missions.
syzygy .......so are you saying these are a product of the camera...?
I believe they are what remains of registration marks, +'s on the film plane which allow mappers to line up adjacent photographs. They were "erased" imperfectly leaving a "ghost" image. These days that can all be done by the software in your camera phone, but at that time it was all cut and paste and blend.
The Data Camera used on the lunar surface during the Apollo 11 mission and later Moon landings was a 500EL with additional modifications. A transparent glass Reseau plate, or register glass, engraved with grid markings was placed between the film magazine and the camera body, immediately in front of the film plane. The plate is engraved with crosses to form a grid and the intersections accurately calibrated to a tolerance of 0.002 mm. The crosses were recorded on every exposed film frame. From the markings, it is possible to calibrate distance and heights in photos taken either on the lunar surface or from space. Such markings were not new or unique to the space program. They were commonly used for large format scientific and aerial photography prior to the Moon landings, when the large size of the photographic negative could be distorted either during exposure or the printing process.

KitsuneFox: syzygy - posts I have made here do not receive much attention. I may do a detailed writeup of the now lost Edgemont Park in PA, one of the first electrified trolley parks in the world, but still debating. I'm missing 1 key bit of information.
