I am asking for a friend who is setting up a spotting scope with an 80 mm telescope. What recommendations do you have for an erect prism diagonal?

For birding, I use a TV Everbright 2 inch Stardiagonal with my 80mm F/7 APO... It's a lot easier to learn to deal with images that are reversed right to left than it is to put up with the loss of sharpness one experiences with an correct image diagonal...
That's my two cents...
