Good advice Stu , mounted , binos will show their best , which is very good 2 eyed views .
As an idea here is my 25x100 Zhumhells , huge and awsome to look thru , but they are way to big to be hand held , these monsters need a mount , so mate if you stick around the 7-10x , 50mm quality binos you wont go wrong .
I remember a night in NZ many years ago when a friend , Terry had a pair of Celestron 10x50 Ultimas , and these performed not to much below my 12x 60's , awsome quality , like any good quality binos , hope you enjoy .
Here is my 25x100's .
