What has the world come to when a refractor on a german equatorial is considered the most manageable option? (from a physical size perspective)
I could think of some criteria where an apo excels - contrast transfer function being one of them - which translates to a more pleasing view when there is a bright object in the fov, but the trade off in raw aperture is something that needs to be considered.
If collimation is viewed as an issue (and cost isn't) there are quality telescopes using reflective components where this problem has been addressed.
I know from my experience when I had a choice between an 180mm starfire and a good 12.5" Newtonian. The refractor collected dust while the Newtonian gathered photons.
