When the seeing is not good, it doesn't matter how much aperture you have, all the stars star to blur together and do not resolve well.

I don't really find this to be the case. Seeing destroys the detail on planets and nebulae for sure, but even in the very worst conditions I have observed in I can easily resolve these objects to the core with the 20". For sure there is plenty of movement and I can't see the tendrils of stars so clearly, but resolve them I can.
I suspect this is due to the sheer resolving power of a big scope - low power is 80 to 200X so can still do the trick even in bad conditions! I love my dob!!!!
