to hold 15x steady one really needs to have them on a tripod - so why not just get a spotting scope - say 20-60 usefull for sighting in as well - I use 10x binos and they can be hard to hold still - one of the best setups I have come across recently is a mate who has a thermal that combined with a spotting scope bees knees - I guess soon a manufacturer will make something that does both
