Thanks Howard,
So my 8" SCT with the ASI034MC camera (1/4" sensor) would have a FoV of 0.19 degrees. Which explains why a telescope higher than F7 or 8 usually isn't used without a reducer. Planets would be the only thing you could video with any chance of a good image to work with.
And adding a 2X barlow would only make that worse...
