Your absolutely right about focal lengths. I've been quite stubborn about deep sky objects and I need to get a scope with a focal length as you say of 600mm or less to maximize the cloud free nights which are few and far between. Also get some nebula filters as the light pollution is chronic around here.
Cheers

So if it is poor seeing you could still use a camera lens or a widefield scope to do some imaging and the result will still be fine.
