Do those include 2" Amici erecting-type diagonals?
If they're labelled "erecting" or "correct image", they
won't work as well for high mag. celestial use.
I was thinking of the conventional Baader 2".
Are there others readily available?

When you sort it that way (and I looked closer) 1 was discontinued and the rest are Amici.

At a dark site one year, since I had run out of star diagonals, I used a WO 90 degree erecting prism on my ZS66 Triplet that I had piggybacked on my C11, which was using a Burgess dielectric. Going back and forth between scopes during the night gave me some interesting comparisions, mainly a difference in field of view, but I didn't think the prism diagonal was that bad. I was targeting clusters, nebulae and galaxies and was quite happy with the nights viewing. The scope being a triplet maybe had something to do with it, but your info will prompt me to try the prism again in some doublets.

Just my thoughts, subject to change at any time.
