Good Questar 7 vs Astro-Physics EDF130 f/6

Does anyone have some experience on the difference in visual performance between these two on the planets? I have the AP130 and want to get a used Q7 (pyrex + broadband coatings) for a step-up in visual performance.

Thanks, Erik

Apples and oranges in my book... but there's no doubt both can produce outstanding planetary images. I do appreciate the aperture advantage of the 7. The cooldown for the Q? That's another matter.
