Scope vs Lens at same focal length

Hi All,

I have a question about using a 560mm scope vs using a 560mm lens with a DSLR.
Which setup would give me better image quality? Is it different for the moon or for stars ?

I'm asking because I own a Canon 400mm F5.6 lens with a 1.4x extender it's a 560mm F8 lens. And somebody offered me a Stellarvue 80mm that is a 560mm F7.1 scope.

What do you think about this battle?

Thanks for the feedback!
Luis
