Hi Eagle Optics,
I am going to do a bird count at an egret rookery and in order to do this I need a scope to move from a tripod mount in a sweep up and down the rookery.
Anyway there is a question of whether I need a straight scope or an angled one?
Thanks for the inquiry. Regarding and angled or straight scope, the issue often boils down to a personal preference. There is no design or performance benefit to one style vs the other.
With an angled scope you can use a shorter/lighter tripod because you don't need to have it raised to eye level. It's also easier for multiple users to share the same scope if it's angled.
On the other hand, some users find the straight body style to be more intuitive to use. My personal preference is an angled scope.
