Based on my (possibly faulty) recollection of my attempts - a 600 and a 2x is just about perfect for a 1.5x crop moon shot; you'd really want a little more for film. Stacking a 2x and a 1.4x would probably be about right, although that might add too much optical softness (as well as increasing the exposure time).
To my eyes it looks as though the bear shot is focussed on the dandelions in front of the bears; the animals themselves look a little soft (photographically, not physically!).
