Refractor vs Mak for planets

How would a Mak 102 or 127 compare to an SV/WO 80 mm f6 "semi-apo" for viewing the planets? Larger aperture, no CA, but less contrast. Which one could you push to higher magnifications?

Of course the refractors can also be used for wide-field work, and the WO has superb mechanics, which might be an advantage when focusing, but I'm just curious about the optics for planetary work at this point.

Thanks.

As for higher mag "pushing," that's much a function of the optic's quality & aperture (for now, we'll ignore atmospheric effects & the human eye). For a given aperture, a more accurate & smooth optic should yield higher useful magnifications. Likewise, for a given optical quality, a larger aperture should yield higher useful magnifications. In this case (4- or 5-inch Maksutov; 80mm SV/WO), the 5-inch Mak should have the higher-magnification advantage (assuming comparable optical quality) -- again, that's "on paper," so to speak. Now, let's reconsider those previously ignored factors (seeing, eyes, et.al)... For observers on most scopes on most nights at most locales, the high-magnification limit is determined by the atmosphere &/or defects in the observer's own eyes (especially floaters).

I would not expect a typical good 4-inch Maksutov to show any advantage over an excellent 80mm refractor, with regard to available/visible plantary detail, regardless of magnification. A 5-inch Mak?, well, that's a bit more interesting. There's a definite aperture advantage, and that 150x-to-200x range will be more "easily" accessed, due to the the Maksutov's longer focal length. As for available/visible planetary detail, the Mak (if it's very good) may have a slight advantage, assuming conditions allow it. If we were to consider a 6-inch Maksutov, then the advantage would be more than slight.

Darn it; is there ever an easy answer?

Cossider instead in this aperture range of Maks, the ITE 5 inch Mak Cass. I am told by Geoff Gaherty that tt's better mechanically, and better optically (Rumak design rather than silvered spot on the corrector). It's on sale now.The weight is the same as the WO semi-apo you mentioned, though the latter will have a vastly larger true field, a great advantage. The views will be brighter in the ITE.
