Thanks Chris. That was a very informative video.
I am amazed at the stated resolution - able to discern a 6 inch object in a 16 mile wide field of view using the Technical Objective Camera (refer ~53:08). I researched it further and that 16 mile wide field appears to be made up of 2.4 nautical mile squares, BUT STILL that's incredible for a 1960s era camera technology, albeit on giant 9 inch wide film ( I read elsewhere 9 x 18 inches) at 110 lines/mm.
If we just take it as being able to discern 6 inches (0.15m) across a 2.4 nautical mile wide field (4.42km) that suggests an equivalent ~29,500 photoreceptors along one side dimension of the film and if the FOV is taken as square, then something like 870,000,000 photoreceptors (think 870 Megapixels in today's money) - on one shot /no mosaic !
AMAZING !!!
Best
