Be interested to hear how it turns out Duncan. My wallet is with Trevor (Newt) and my imagination with Alex!
I always knew my budget would be limited, and have been over the moon with what's possible with an 8" Newt - will keep me plenty busy for a while to come. Ezystyles (Eric) is many people's idol on the newt imaging side here at IIS. Don't know if you're familiar with his work, but pretty much all done with 8 and 10" Newts with corrector and pollution filters:
