Has anyone compared 180mak to C11?

Recommended Posts

Has anyone seen a 180mak ' out perform' a C11? 

By this, I mean specifically with respect to seeing double stars and planetary detail. 

I know aperture should win, but I'm interested in real world accounts where side by side comparison produced surprisingly better results for the mak over the C11

Thanks

I've used several 180 Maksutov Cassegrains and  observed at length with a C14, as well as several other SCT's over the years. Though both designs are very good, I would lean towards the 180 Mak for double stars, simply because I've not yet seen a Schmidt Cassegrain give a true star image. In the SCT stars always seem to appear as tiny soft ping pong balls rather than a true Airy disc with diffraction rings. So by extension, I'd go for the Mak as a prefered planetary scope, simply because if it shows a sharp Airy disc it will show sharp planetary detail. Soft stars = soft planetary detail, and although the C11 has significantly greater resolution, unless it is truly thermally stable the benefit may be lost in the softer view.

I second that, i have put my 150 Mak head to head with my 8" LX200, the Mak is smaller but, produced sharper planetary views, and yes, from what i saw, my Mak produced star images as close to a frac as i've seen.
