If you want to do deep sky, then look to a Losmandy G11/Celestron CGE or if you can find a 2nd hand Celestron CI700...
For planetary a 12" F/5 can be done, but it will take a bit of doing, not to mention 4 hands to set it up...
I have no troubles with an 11" SCT on my EQ6, but the C11 is only 2ft long, the newt would be closer to 5.5ft long I think..
there are a fair few people successfully using a 10" newt on an EQ6 for deep sky imaging, so dont write that idea off, as a 10" newt is a lot cheaper than a 10~11" SCT..
Mikes comments above about an 8" F/6 on an EQ6 are perhaps a little conservative, my EQ6 didnt even break a sweat with my 8" newtonian.. And there are forum members who've very successfully used 8" F/6 newts on HEQ5 mounts.....
