Looking for a good quality 2" star diagonal, and also an erecting prism, either 1.25" or 2".

cheers

TAKE CARE I have tried 2" erecting prisms they do NOT reach focus in any of my scopes just the 1.25"

Yes, the erecting prisms do have a slightly longer light path. I have 1.25 and 2 inch erecting prisms but have not had any trouble gaining focus with them. My scopes have obviously got enough back focus.

Sab, I have sent you a PM.
