1.25in. Orion Prism Star Diagonal
Reviewer: G. Wang
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.
