How can I get a WIDE field?

Guys,
I'm wondering how someone might get a wide field view, preferably with aperture, for visual use.
It seems that the bigger the scope, the less width of field you get.
Now I think there are probably two options:

1) Meade 5000 80mm refractor. Fitted with a 35mm Panoptic eyepiece, would give a field of a bit over 5 degrees, similar to binoculars. The aperture is a bit small though.

2) 8" SCT with f3.3 focal reducer. Fitted with a 35mm Panoptic eyepiece, would give a field of 3.6 degrees.

Can you see any major issue with either of these set ups? I know the f3.3 is said to be for photographic use only, but surely if a camera records the image well, then the eye must be able to see it?

Cheers,
Jason.
