It doesn’t mean you shouldn’t try, if you happen to have a mak (or SCT).
Many great images on Astrobin from cassegrains of all sorts - Maks, SCTs, Mewlons and more.

I think you misunderstood what I said.
A Newtonian has terrible coma and field curvature and it needs field correction lenses to make it into an astrograph, but for viewing or imaging the planets those aberrations are not significant because of the small angular size of the objects.
The lack of very good planetary images made with Maksutovs is only partly due to the fact that there are no large Maks available.
