Hi,

the large body Kowas (770 and 880 series) can use 1.25" astro EPs with an adapter. Not all will come to infinity focus though. The grub screw adapter helps a bit with that. Search cloudynights and here for some examples that come to infinity focus.

thank you joachim for that important caveat. the possibility of using 1.25" eyepieces also raises the question of acceptable field stop diameters - which i assume vary with scope. somewhere around 24m for most? this does not seem to be part of spotter documentation from the manufacturer (not that i would expect it to be). thank you!
