Hi all
i know this has probably been asked countless times, but if we assume portability is not an issue, is the 12" dob a better option than the 10, or will i have more troubles with issues such as seeing and time to temp equilibrium with the larger mirror? will the larger mirror have more troubles with dancing, shimmering images? these questions may seem daft

, so apologies for that, but this is such a good site that i feel almost comfortable in asking anything that bugs me before deciding on a scope.
thanks again
adam
