For extreme long distance nothing beats a spotting scope but those big binoculars on a carbon fiber monopod carried in your back seat would be great for wider angle views and wildlife spotting. Nothing beats using two eyes in a binocular.
That's the goal which is why I pay attention to eye relief with my glasses and the Field of View.
My spotting scope is really nice but, it is a bit like looking at the world through a soda straw.
