I'm looking for a 2" diagonal for the 4" f/7 refractor in my sig, and I decided to get a prism after reading this report (pdf warning) from our own Bill P. It seems as though the Baaders are top of the line, so I guess that's what I'll go for. But there are a few different prism diagonals offered by Baader, at wildly different prices, so I want to make sure I know what I'm getting.
I see 3 different Baader 2" prism diagonals from Agena Astro. From least to most expensive:
The comparison report linked above evaluates a Baader Zeiss prism and a Baader Zeiss prism with Clicklock. I would assume that a Zeiss prism is preferred to an Amici prism given the $240 price difference between the first two linked above, but oddly enough the $720 diagonal has an Amici prism. Color me confused.
I guess my question boils down to this - can I expect premium performance from the $300 Amici prism diagonal, in line with what was reported in the shootout?
