I tested the Baader 2" Amici Prism Diagonal on my Lunt Engineering 102mm ED refractor with my Quark Chromosphere to obtain correct image of Sun, orientated like GONG images and this is my review:
First,it is a BEAUTIFULLY machined diagonal.
I used it with William Optics Binoviewer and matched 32mm and 25mm Plossls.
I compared it with another 2" Di-Electric diagonal.
Result: I see NO DIFFERENCE between the 2 diagoanals,with,of course,NOW the Suns image is correctly orientated, no East-West flip.
I highly recommend this for those looking to see up close,correct image views of our Sun,using a Quark and a refractor.
