In general, what advantages does a slow 'scope have over a fast one?

Easier to get the figure of the optics within acceptable limits.

More forgiving on eyepieces generally.

(Assuming same aperture) the slower scope will need a longer fl eyepiece for the same mag, therefore better eye relief and eyepiece aberrations easier to control (eyepiece lenses less highly curved).

Best,
Stephen
