I was looking at a website earlier specializing in lunar imaging. She had a big ol' AP that was f/28.

f/28? Do scopes like this have to be specially made or is there a gizmo that would be a counterpart to a focal reducer?

A barlow? I notice a lot of the times a photo's credits will say @f/35 or something. Indicating that they stacked barlows/eyepieces?

Just a guess.
