Comment: 
RKS0804+1217 has a faint companion to its SW; out of the fiber. RKS 0850+0751AB, I cannot see but one star (no companion) so, guided with the main star. RKS1121-2027AB : B, the not precisely faint companion, is too close to A and thus unresolved and in the fiber, same as A. Completed the program with the Sun at -10.8 degrees of elevation. It was a 'hot' (~ 18.5C) clear night with a seeing not quite stable but good enough.
