I'm sure Paul said this was the equivalent of stopping down. I know the scope starts with an Ap of f7.5, but  how stopped down this would end up. i dont know. Paul will likely know though.As you say, this is probably whats happening when baffling the barlow, but i dont know for sure.As for the Owls, I dont see enough of them to throw away bad quality pics, but i'll keep at it Steve..she or he is a beauty and i'd love some closer shots so the scope and myself are not struggling with focusing</blockquote>
