Long focal ratios may not be so bad?

When doing visual astronomy, lower power means brighter image, wider field, but less detail in image.

Magnification somewhat seems to bring out more detail and noticed it in the likes of the Orion Nebula.

I know in astrophotography, its always shorter focal length the better approach, because of being faster photography easier tracking, wider field, but the tradeoff maybe less detail and resolving power?

Would a longer focal length scope even though its slow photographically and harder to get good tracking allow more image detail?
