Ive got one of the devices freestatehunter recommended. I put it on an un mounted scope so i could take pictures of deer with my phone while i was in the shooting house. I had a really hard time holding it still enough to see the deer. I imagine a spotting scope would make it much easier. Theyre pretty cheap so youre not out much if it dont pan out. Having it on a gun might help too. However, if holding the gun steady is the problem already, i dont think this will help much
