Erik, I'd really like your help when I make the 6" f/10 refractor on a Gerrish mount. It could be the perfect ADA scope for chair-bound users, without resorting to a video feed to a screen.
Actually the 6" f/5 might be better for ADA, we'll see what the final eyepiece height turns out to be. Another advantage of a Gerrish mount is that it can be polar-aligned with a laser, good enough for visual use and maybe imaging.
