Are the BBHS coatings easy to clean? Do the coatings have a life comparable to your dielectric coatings? Do the coatings degrade over time and at what rate? Is there a difference in performance between your dielectric diagonal and the BBHS one, what are the differences and are they significant or very slight? I own an early Televue APO 4 inch refractor.

Which accessories do I need to connect this diagonal to a Celestron Edge HD 8? I think I may directly screw the diagonal to the tube but is there another alternative as I also use the focal reducer.

And what about the eyepiece? Is it compatible with 2’’ and 1.25’’?

What is the "glass path" length of 50mm? Is the optical length the physical length/refractive index? That would make the physical glass path 74mm for BaK-4?(not 50mm) It says 31mm clear aperture but in the pictures it looks like the edges of the prism are clipping the aperture mask- is it really 31mm circular aperture unvignetted through the glass? Thanks!

Baader T-2-/ 90° Astro-Amici Prisma
Bei ersten Tests machte das Amici-Prisma auch bei höheren Vergrößerungen eine guten Eindruck. Das bestätigte sich auch im Vergleich etwa mit dem Baader 2" ClickLock Zenitspiegel und dem Baader 2" BBHS Zenitprisma.

Das Amici-Prisma hat bei einem ersten Test einen guten Eindruck gemacht, auch bei höheren Vergrößerungen.
Ein Vergleich mit dem Baader 2" BBHS Zentiitprisma und dem 2" Baader ClickLock Zenitspiegel zeigte keine Nachteile.
