Buying a Kowa spotter, leaning towards 88a. I’ve read a decent amount on the bird watching forums and it sounds like they will buy 3-4 of the same scope, line them all up, and pick the best example. Is this necessary? Is there that much variation from scope to scope when you’re paying $3200? If it is, anyone have pointers on how to appropriately test them? The “star” test is mentioned there a lot, but no reference to what that actually is.
