There seems to be a certain amount of conjecture regarding large scopes on not so large mounts for imaging.
As far as the original question of could a 12 inch scope be visually used on an eq6 .... Yes it can, and quite well so.
On to the imaging ( deep sky) there is obviously a differing opinion as to can it be used. Well let me use the analogy of a car race, could you use a standard Holden commodore at Bathurst in the race.... Well yes you could, but it's level of performance isn't really of a quality that would satisfy most racing drivers, and you would find if you went into a corner at the speed of the better cars, you would end up in the trees or a wall.
Likewise with the imaging, whilst yes you can mount the 12 inch on the eq6 the performance will be somewhat similar to the race analogy, you will be able to do 2 min exposures consistently maybee even 4 or 5 minute exposures if you are really lucky. But you will not get consistent 20 minute exposures even with a f 4.9 scope, much less at f11. So the question then becomes what will you settle for, if you are happy with 2-3 minute exposures .... Great, but all those who have progressed past that point have said consistently it's not an appropriate choice for such a setup, and have been imaging successfully for years. If there is any doubt as to the veracity of my claims then you can search through the forums for images, taken on such equipment.
