That`s a big camera! do 8 1/2"x11" negatives of the whole sky and blink them!
FWIW, most of the recon cameras are not all that well color corrected and are normally used with filters to fix that problem. They didn`t have any problems with light levels so they could throw away a lot of the light that came to them with the necessary filtering.
That is a lot of glass tho and the 9.8" diameter and F6.3 makes an EFL of 62" and a FOV of about 8 degrees and about .9 degree/in. of scale on the film providing that my calcs out of the top of my head are right.
