I have this nice little ED80 OTA and it gives smashing images. I want to use it for terrestrial viewing. Are there any opinions about the Amici (roof) prism type erecting diagonals? I can't find much in the way of diagrams of the optics; the only one I found shows a 90° version, which is not as convenient as a 45° version
I only have nice 2" eyepieces, which limits what's available. Seems like there is no cheap solution. There is apparently a limit to magnification with these prisms. Are the cheaper ones worse in this respect?
