My current main 'scope is an Orion Optics Europa 250. It's a 10" (ish) f4.8
device.

I've seen the new Sky Watcher Pro series and I'm rather taken by the 150mm
f12 Mak. At 440UKP for the OTA it's quite nicely priced as well.

The question I have is: with it being f12 is it likely to give better planetary
performance than the f4.8 Europa? This is assuming equal optical quality.

Many thanks.

Jim
