Godbound, Word of Bow... would you allow None Beyond Reach, Omnipresent Reach, The Seeking Flight, et al to be used with a scope/cyber eyes/scrying/gifts of far seeing?
The first two Gifts you list say "natural" sight, so for them I'd say no. However, The Seeking Flight doesn't have that restriction, so I'd say yes for that one. The Seeking Flight would, in my opinion, stack with the other two if the PC had all three Gifts.
I feel that the intention of 'natural' is to differentiate between non-supernatural and supernatural sight, so I would allow that in my games
