When I popped this baby in to my scope, it was severely miscollimated. Stars looked like comets even at low power. I could tell by the defocused image that it could be a good diagonal if aligned. After some tinkering, the prism was aligned and it gave very nice images of Izar and Saturn in my 100ED. I needed a diagonal in a bad way, so returning wasn't an option, but the story has a happy ending. It's a nice diagonal if it comes aligned.
