G'day Michael,
I cannot remember the exact details of the Fuji 10x70 objectives but they are about f/4 or a little quicker. You should be able to use answers something like:
1/ Focal length = 280mm
2/ Objective diameter = 70mm (two eyes by 70mm each is not the same as 140mm, a good starting point is to pretend that it is a 70mm aperture telescope)
3/ Ocular focal length 28mm (yields 10x) and apparent field of view 53° (yields 5°18' true FOV)
4/ The Fuji FMT 10x70 does indeed have a 5°18' (or 5.3° if you prefer) true FOV
5/ I've no idea what Stellarium uses but a typical human field of view is something like ~100° vertically and quite a bit more laterally (much of it low resolution peripheral vision)
All the best!
