Do I win the prize for the widest field newtonian on IIS ?

So when you putting the ED80 on it for a finder scope?
I sold the ED80 after buying this one and seeing how much brighter it was
The R130 kills the ed80 as a visual scope.

Hey Geoff, assuming the secondary is large enough, I calculate the 31 Nagler should give you just under 4 degrees TFoV. Wow, not bad
Yep the 31 nagler has been in it, but Im sorry to report that such a wide fov on an f5 scope comes at an unfortunate cost of excessive coma

My 24mm panoptic gives a 2.5 degree view which is enough, so the ideal would be a nice 1.25" focuser, but do you think I can find a suitable one?
I was considering the JMI 1.25" crayford which was for sale here, but the problem with that is that the drawtube is 3 inches long, and the inner diameter is 1.25" and not bigger, meaning that Im going to get vignetting
