I know, right? I could not find any reviews on forums at that time and took a chance on it.
I'm a little surprised there aren't many reviews of this nor even with the 2" APM prism diagonal (it looks to be identical with apart from the branding) which now looks to be discontinued by them.
What's the performance of this like in comparison to your Baader Zeiss prism? Have you seen any real difference?
It's a bit tricky to do side by side diagonal comparison. I can tell that with both prisms I can push scopes to their limits, so if there are differences they are minor. Stepping from mid level dielectric to quality prisms was quite obvious (considerable performance improvement on planetary, lunar and doubles). Between the prisms nothing jumps in, so I use them interchangeably.
