Well, it is a well known that in some universes a double negative results in a positive result. I'm interested in taking an attempt at imaging OSCAR satellites. Any tips from the community for say, AO-7, using an optical telescope and a DSLR mounted at its focus?

With any luck, AO-7 will outlive (or perhaps it already has) the IBM punch card that caused the whole 5-digit thing in the first place. Of the constants in the universe, the first one is 42, immediately followed by either 72 or 80, depending on your background. We apparently had programmers define the KEPs format, as both lines are 71 characters long... :)

(For source code, columns 73-80 were reserved for sequence numbers, so that when you dropped your deck, the cards could be reassembled in the proper order.)
